The system consists of a transmitter and an ultrasonic transducer. The transducer contains a piezoelectric crystal that has the ability to convert electrical signals generated by the transmitter into ultrasonic pulses. The unit operates by directing ultrasonic pulses, or sound waves, through the air toward the liquid surface. They are then reflected off the liquid surface as an echo, and returned to the transducer. The piezoelectric crystal then converts the returned echo into an electrical signal which is analyzed by the transmitter. The elapsed time between the generation of the ultrasonic pulse and the return echo is proportional to the distance between the face of the transducer and the liquid surface. TYPICAL MOUNTING CONFIGURATIONS channel flow installation with the transducer mounted on a bracket. Figure 2 shows how the unit can be mounted in a coupling or flange for level or volume applications. The transducer is installed above the liquid surface. A minimum dead zone distance of 18" (457 mm) must be allowed between the face of the transducer and the maximum attainable level.

Figure 3 shows how the transducer can often be mounted further down in a wet well or sump if the liquid will never reach the top of the vessel. This helps to keep the Figure 3 Typical Transducer Mounting - Wet Well or Sump ULTRASONIC BEAM ANGLE liquid surface. The chart below shows the distance the transducer should be located away from side walls and obstructions. The distances are based on a 6° beam radius at different heights above the liquid surface. Generally speaking, the transducer should be mounted one foot away for every 10 feet of height. A 12° conical beam of ultrasonic energy is emitted from the face of the transducer. The transducer should be mounted in a location such that the ultrasonic signal does not touch the side walls or any other obstructions in the vessel. This is typically accomplished by using a bracket, half-coupling, or rigid conduit to mount the transducer in a spot where a strong echo can be received off of the Distance from Transducer Face (feet) 3' 6' 9' 12' 15' 18' 21' 24' 27' 30' 33' 12° Beam Diameter (feet) 0.6' 1.3' 1.9' 2.5' 3.2' 3.8' 4.4' 5.0' 5.7' 6.3' 6.9' Minimum Distance from Wall or Obstruction (inches) 4" 8" 11" 15" 19" 23" 26" 30" 34" 38" 42" 3 AGENCY AGENCY APPROVALS PROTECTION METHOD AREA CLASSIFICATION MODEL FM 300-RXXX-45X 301-RXXX-400 with 384-XKXX-0XX Indoors & Outdoors NEMA Type 4X & IP 65 Hazardous locations Class I, Div. 1; Groups B, C & D Class II, Div. 1; Groups E, F & G Class III TYPE 4X enclosure CSA 300-RXXX-45X 301-RXXX-400 with 384-XKXX-0XX 300-RXXX-45X 301-RXXX-400 with 384-XK0X-0XX 384-XK1X-0XX and 384-XKYX-0XX Non-hazardous Hazardous locations Class I, Div. 1; Groups B, C & D Class II, Div. 1; Groups E, F & G Class III Class I, Div. 1; Groups C & D Class II, Div. 1; Groups E, F & G Class III Hazardous locations These units have been tested to EN 50081-2 and EN 50082-2 and are in compliance with the EMC Directive 89/336/EEC.

Select one condition from each of the operating parameters that best describes your application. 2. Enter the corresponding performance multiplier value in the application column. 3. Multiply all values together. 4. Obtain the maximum range from the table below that corresponds to your switch or transmitter model. 5. Multiply step 3 by step 4; this yields a value that is the maximum allowable measurement range for this application. Example: The vessel is a closed-top tank, uninsulated, 22 feet tall. Surface agitation: Vapor and steam: Expect slight agitation from fill line. Performance multiplier 0.9 The process temperature is +130° F; slight vapor is expected. Performance multiplier 0.9 Ultrasonic non-contact devices are typically rated for a maximum range in ideal conditions. Experience has shown that maximum range must be adjusted for certain factors. Although the maximum range rating is somewhat conservative, each application must be evaluated for specific conditions. The operating parameters listed below can impact the maximum range of measurement: • Surface agitation • Vapors and steam (as measured by temperature difference between liquid and air) • Beam spread interference • Sensor alignment • Foam • Dust • Air movement • Ambient temperature • Pressure Sensor alignment Beam interference: No interference exists. Performance multiplier 1.0 Temperature Pressure Air movement Beam spread interference Sensor alignment: The sensor will be perpendicular to the liquid surface. Performance multiplier 1.0 Foam: Dust: Air movement: Ambient temp.: Dust Beam spread interference None. Performance multiplier 1.0 None. Performance multiplier 1.0 None. Performance multiplier 1.0 0 to +120° F. Performance multiplier 1.0 Atmospheric pressure. Performance multiplier 1.0 Pressure: Foam Vapors Surface agitation Will the Model 300 work for this application? Calculation: Multiplied values of all application columns: 0.9 x 0.9 x 1.0 x 1.0 x 1.0 x 1.0 x 1.0 x 1.0 x 1.0 x 30 feet (maximum) = 24.3 feet The calculation yields 24.3 feet as the new maximum range. Since the tank is 22 feet tall, this application will give satisfactory results. NOTE: The performance estimates provided are conservative estimates. Since these factors are subjective, the estimates have been designed to provide very high confidence of system success. Contact the factory if there are any questions concerning the interpretation of any of these values. 6 MEASUREMENT OPERATING PARAMETER RANGE CALCULATIONS CONDITION PERFORMANCE MULTIPLIER APPLICATION SURFACE AGITATION: Surface agitation or waves can degrade the performance. Moderate agitation results in only slight degradation of performance. The worst case is when the surface is a good reflector, but in the wrong direction. (Refer to sensor alignment.) VAPOR AND STEAM: Vapors in the air space, above the process, become apparent, and cause problems when the liquid process temperature is well above the temperature of the airspace. The greater the difference, the more expected vapor problems. The problems result from condensation or layering in the sound path, both of which attenuate the sound signal, degrading performance. Avoid steam if possible. To avoid these problems, ensure that the vessel is insulated so that vapors are less likely to condense. If a vent is used, be sure that the vent, which is where condensation will form, is well away from the sensor. BEAM SPREAD INTERFERENCE: It is strongly recommended that nothing be allowed within the sensor’s beam, except the liquid which is being monitored. Often, the signal from the liquid will be strong, compared to the signal from other sources, such as, ladder rungs filling process material, support struts, etc. For that reason,some applications may provide satisfactory results, even with than 60 interference. Interference from agitator blades is only an intermittent interference that usually has little effect on performance. It is recommended there be no interference within the 6° half angle of the sensor beam. If interference is unavoidable, make the interference as far as possible from the sensor so that the real signal at the longest distance is stronger than the interference signal. SENSOR ALIGNMENT: Optimum performance is obtained when the sensor is perfectly aligned. If the process is not perpendicular to the sound beam, the sound will not reflect properly back to the sensor. The effect is significant. FOAM: Even small thicknesses of foam can attenuate the ultrasound and render the system inoperative. If possible, moving the sensor to an area in the tank where there is less foam, will improve the performance. Thick, heavy density foams can sometimes produce a reflection from the top of the foam. The multipliers shown at right are general guidelines. For further assistance consult the factory. DUST: Dust attenuates the sound and results in poor performance. Even barely perceptible haze in the air can cause significant attenuation.

This will be most noticeable in applications where vapors or steam tend to form. AMBIENT TEMPERATURE: The ambient temperature can have a significant effect on the sound and on the sensor’s capability to transmit and receive sound. The most noticeable effect on the sensor is at the temperature extremes. PRESSURE: Sound requires air molecules to be able to travel. Sound will not travel in a vacuum. Likewise, higher pressures will allow the sound to continue without decay, which can cause problems with multiple echoes. -20° to +140° F (-29° to +50° C) . . . . . .1.0 -40° to -20° F (-40° to +29° C) . . . . . . . .0.9 +140° to +160° F (+50° to +70° C) . . . .0.9 -10° to +50 psig (0.689 to +3.45 bar) . .1.0 Pressures outside above rating . . . . . . . . . . . .Consult factory Multiply all values together in the application column Choose a range value from the Maximum Range Table Maximum allowable measurement range for this application x 7 TRANSMITTER Supply voltage SPECIFICATIONS 120 VAC +10%/-15%, 50-60 Hz 240 VAC +10%/-15%, 50-60 Hz 24 VDC, ±20% Power consumption Analog output signal Active mode Passive mode Digital output Relays Fail-safe Ambient Temperature Display Keypad Humidity Fuse (Non-replaceable) Electronics Electronics 12 watts (without heater) 4–20 mA (isolated) maximum 1,000 Ω loop resistance 4–20 mA (isolated) loop resistance dependent on power supply (32 volt maximum) 1,000 Ω @ 24 volts RS–485 with Modbus 10 amp SPDT resistive (none, 2, or 4) User selectable for analog and relay outputs -40° to +160° F (-40° to +71° C) Two-line alphanumeric LCD (16 characters per line) 16-button 99% non-condensing 3 ⁄8 amp, 250 VAC Slo-Blo® for AC units 11⁄2 amp, 250 VDC Slo-Blo® for DC units TRANSDUCER Transducer Frequency Maximum Range Maximum Span Deadband Ambient Temperature Temperature Compensation Operating Pressure Beam Angle Cable length SPECIFICATIONS 38 kHz 30 feet (9.1 m) 28.5 feet (8.7 m) 18 inches (460 mm) minimum Transducer -40° to +163° F (-40° to +73° C) non-operational to +250° F (121° C) Automatic over range of transducer operating temperature –10 to +50 psig (–0.689 to +3.45 bar) Conical 12° 500 feet maximum (between transducer and electronics) PERFORMANCE Response time Accuracy SPECIFICATIONS 2 seconds typical ±0.25% of calibrated span 8 300 INTEGRALLY NUMBER MOUNTED TRANSMITTER MODEL Models available for quick shipment, usually within one week after factory receipt of a purchase order, through the Expedite Ship Plan (ESP) BASIC MODEL NUMBER 300 Integrally mounted transmitter INPUT POWER 0 1 2 120 VAC, 50/60 kHz 240 VAC, 50/60 kHz 24 VDC OUTPUT SIGNAL 1 3 5 4-20 mA isolated RS-485 with Modbus 4-20 mA & RS-485 with Modbus RELAY OUTPUT 0 C D No relays Two 10-amp SPDT relays with gold flash contacts Four 10-amp SPDT relays with gold flash contacts TRANSDUCER G L 2" NPT Kynar, 3" insertion length, 2" NPT Kynar, 10" insertion length 3 0 0 R 4 5 9 301 MODEL REMOTE NUMBER MOUNTED TRANSMITTER Models available for quick shipment, usually within one week after factory receipt of a purchase order, through the Expedite Ship Plan (ESP) BASIC MODEL NUMBER 301 Remote mounted transmitter INPUT POWER 0 1 2 120 VAC, 50/60 kHz 240 VAC, 50/60 kHz 24 VDC OUTPUT SIGNAL 1 3 5 4-20 mA isolated RS-485 with Modbus 4-20 mA & RS-485 with Modbus RELAY OUTPUT 0 C D No relays Two 10-amp SPDT relays with gold flash contacts Four 10-amp SPDT relays with gold flash contacts 3 10 0 1 R 4 0 0 MODEL MODEL 384 KYNAR TRANSDUCER NUMBER PROCESS CONNECTION 2 5 1" NPT, not available with transducer housing code 1 or Y 2" NPT TRANSDUCER HOUSING 0 1 Y No housing, 35' (10.7 m) of cable potted into transducer Cast aluminum, NEMA 4X/7/9 housing with 3⁄4" NPT single conduit, connecting cable ordered separately 316 stainless steel, NEMA 4X/7/9 housing with 3⁄4" NPT single conduit connecting cable ordered separately TRANSDUCER MOUNTING BRACKET 0 3 4 ➀ No mounting bracket Wall mount bracket for 2" NPT process connection only Floor mount bracket for 2" NPT process connection only ➀ Transducer mounting bracket not available with 1" NPT process connection.
