Product catalog summary
Product Overview
The LPG10-1000 Liquid Flow Sensor is a compact, bio-compatible sensor designed for non-invasive liquid flow measurement using CMOSens® planar packaging technology. It provides a fully calibrated, temperature-compensated digital output via I2C interface.

Key Features
  • Ultra-small size for easy integration.
  • Excellent repeatability and accuracy.
  • Bio-compatible materials with inert properties.
  • Calibrated digital output with temperature compensation.

Performance Specifications
The sensor operates with a full-scale flow rate of 1000 µl/min and a sensor output limit of 1500 µl/min. It maintains accuracy within 5% of the measured value or 0.25% of full scale, whichever is larger. The repeatability error is 0.5% of the measured value or 0.025% of full scale. The sensor operates within a temperature range of +5 to +50 °C and a humidity range of 0 to 95% RH.

Electrical and Communication Specifications
The sensor operates at a voltage range of 3.3–3.6 VDC with a typical current of less than 6 mA. It communicates via a standard I²C interface with a default address of 64 (hexadecimal: 40).

Mechanical and Fluidic Specifications
The sensor's dimensions are 10 x 10 x 2.25 mm with a total mass of 0.32 g. The fluidic connection is downmount, and the internal substrate flow channel is made of borosilicate glass. The pressure drop at full-scale flow rate is 0.1 mbar.

Ordering Information
The standard shipment includes only the sensor. An Evaluation Kit and a Connectivity Kit are available for easy testing and integration.

Important Notices
The sensor should not be used as a safety or emergency stop device. It is sensitive to electrostatic discharge (ESD) and should be handled with appropriate precautions. The warranty covers defects in material and workmanship for 12 months from the date of delivery.

Compliance
The LPG10-1000 complies with REACH, RoHS, and WEEE directives.

Liquid Flow Sensor LPG10-1

LPG10-1000 Liquid Flow Sensor digital output (l2C) Digital Planar Package Sensor ■ Ultra small size ■ Excellent repeatability ■ Bio-compatible & inert materials ■ Calibrated and temperature compensated 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, temperature-compensated 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) aFlow rate at which the sensor output saturates, see section 2 for performance specifications between full scale and saturation point bFlow path empty 'Pressures listed are mechanical limits of the glass substrate; Burst pressure of manifold assembly depends on actual manifold seal design. www.sensirion.com Version 3 - January 2017 1/5
