LPG10-1000

LPG10-1000 Liquid Flow Sensor Digital Planar Package Sensor     Ultra small size Excellent repeatability Bio-compatible & inert materials Calibrated and temperature compensated digital output (I2C) Product Summary Unique CMOSens® planar packaging technology enables non-invasive measurement of liquid flow inside a cost-effective planar form factor. The flow channel passes through the planar substrate and is connected to fluidic channels via a manifold. The fluid is only in contact with the glass channel. The digital microsensor chip provides the full signal processing functionality for a fully calibrated, temperaturecompensated digital output. Integration of the LPG10-1000 Liquid Flow Sensor Due to the dramatically reduced size and downmount fluidic connections, the LPG10-1000 allows an outstandingly compact mechanical, fluidic, and electronic integration. To receive support and acceleration on initial testing, please contact Sensirion about existing integration solutions. 1 Sensor Performance Table 1: Performance of LPG10-1000 (all data for medium H2O, 23 °C, 1 barabs unless otherwise noted) Parameter LPG10-1000 Unit Full scale flow rate Sensor output limita Accuracy below full scale (whichever error is larger) Repeatability error from zero to full scale (whichever error is larger) Temperature coefficient (additional error / °C; whichever is larger) Flow detection response time 63 Response time on power-up Operating temperature Operating humidity Storage temperatureb Storage humidity Recommended maximum operating pressurec Burst pressurec 1000 1500 5 0.25 0.5 0.025 0.1 0.005 40 120 +5 … +50 (+41 … +122) 0…95%, non-condensing -40 … +60 (-40 … +140) 0…95%, non-condensing 3 (43) 7 (101) l/min l/min % of measured value % of full scale % of measured value % of full scale % of measured value / °C % of full scale / °C ms ms °C (°F) % RH °C (°F) % RH bar (psi) bar (psi) aFlow rate at which the sensor output saturates, see section 2 for performance specifications between full scale and saturation point path empty cPressures listed are mechanical limits of the glass substrate; Burst pressure of manifold assembly depends on actual manifold seal design. bFlow www.sensirion.com Version 4 – January 2019 1/6 LPG10-1000 Liquid Flow Sensor 2 Specifications Chart LPG10-1000 Absolute Accuracy with H2O 100 10% 5% At 23°C At 6°C/40°C Repeatability 0% -1500 -1000 10 1 At 23°C At 6°C/40°C 0.1 Repeatability 0.01 -500 0 500 Flow rate (µl/min H2O) 1000 1500 Figure 1: Sensor accuracy and repeatability (% of measured value) across the sensor’s flow range 3 Accuracy (µl/min) Accuracy (% of measured value) LPG10-1000 Relative Accuracy with H2O 10 100 1000 Flow rate (µl/min H2O) Figure 2: Sensor accuracy and repeatability (µl/min) across the sensor’s flow range Communication with the Sensor The OEM flow sensor LPG10-1000 shows bidirectional, linear transfer characteristics.

The physical interface consists of two bus lines, a data line (SDA) and a clock line (SCL) which need to be connected via pull-up resistors to the bus voltage of the system. By default, the I2C address is set to 64 (hexadecimal: 40, binary: 1000000). These lines can be used on a 3.3 V level with a clock frequency of 100 kHz. For the detailed specifications of this I²C communication, please refer to specific I²C Application Notes from Sensirion. www.sensirion.com Version 4 – January 2019 2/6 LPG10-1000 Liquid Flow Sensor 4 Fluidic Connection Table 4: Fluidic Specifications and Pressure Rating Parameter LPG10-1000 Wetted materials:  Internal substrate flow channel material Fluidic connection 5 Borosilicate glass Downmount Pressure drop (at full scale flow rate, H2O, 23°C) 0.1 mbar Total internal volume ~11.7 l Mechanical Specifications Table 5: Mechanical Specifications (for tolerances please see the drawings below) LPG10-1000 Parameter Largest dimensions Total mass Cross section flow channel ~10 x 10 x 2.35 mm ~0.32 g ~0.9 x 0.9 mm All dimensions in mm Attention fragile! Mechanical shocks and touching or probing of the glass surface may lead to stress on the chip and may damage the glass package.  The thin-walled top layer can easily break. Thus, do not touch the planar glass package on the top surface with your fingers or tools (e.g. tweezers).  Respect the burst pressure specification. Be aware that injecting fluid by hand with a syringe can lead to large pressure peaks.  Do not exert pressure on the sensor chip. Mechanical structures must not be in contact with the sensor chip (see bounding box above).  Do not operate the liquid flow sensor when the contact pads have been wetted. Dry first. www.sensirion.com Version 4 – January 2019 ! 3/6 LPG10-1000 Liquid Flow Sensor 6 Ordering Information Standard shipment includes only the sensor, neither cables nor fluidic connection material. For easy testing, an Evaluation Kit is available. The kit contains: One LPG10-1000 sensor, preassembled in a fluidic manifold (PMMA), featuring ¼ -28 flat bottom fluidic fittings. The fluidic seal between sensor and manifold is ensured using two O-Rings (FKM). The included connector cap secures the sensor to the manifold and features a 4-pin Molex connector. The included Molex adapter cable, USB-cable and software allow for easy evaluation using a PC. When using the Evaluation Kit, the wetted materials include PMMA (manifold) and FKM (O-Rings), as well as borosilicate glass (LPG10 sensor). For integration support, please see the Application Note “Engineering Guidelines for LPG10 Integration”. The connector cap included in the Evaluation Kit can be purchased in combination with the LPG10-1000 sensor. Contact Sensirion for more information on the Evaluation or the Connectivity Kit.
