Liquid Flow Meter LS32-1500

Product catalog summary
Product Overview: The LS32-1500 is a compact liquid flow meter designed for precise, non-invasive measurement of liquid flow rates up to 40 ml/min. It features a 20 ms response time, excellent repeatability, and high chemical compatibility due to the use of stainless steel, PTFE, and PEEK materials.
Sensing Performance: The sensor provides accurate measurements with a full-scale flow rate of 40 ml/min and a sensor output limit of 65 ml/min. It maintains accuracy within 5% of the measured value or 0.25% of full scale, whichever is larger. The repeatability is within 0.5% of the measured value or 0.025% of full scale. The operating temperature range is +5 to +50°C, with a recommended maximum operating pressure of 12 bar.
Communication and Electrical Specifications: The LS32-1500 uses a digital I2C interface for communication, with a default address of 64. It operates on a power supply of 4.0 to 6 V and has an operating current of 5.1 mA. The sensor pinout includes SCL, VDD, GND, and SDA connections.
Fluidic and Mechanical Specifications: The sensor's wetted materials include 904L stainless steel, PEEK, and PTFE. It features 1/4-28 flat bottom fluid connector ports and a pressure drop of 2.15 mbar at 40 ml/min. The sensor's dimensions are 59 x 18 x 18 mm, with a total mass of approximately 30 g.
Important Notices: The product is not intended for use as a safety or emergency stop device. It is sensitive to electrostatic discharge (ESD) and requires appropriate handling precautions. The warranty covers defects for 12 months from delivery, provided the product is used within specified conditions.
Compliance: The LS32-1500 complies with EU directives on REACH, WEEE, and RoHS, ensuring it meets environmental and safety standards.

LS32-1500 Liquid Flow Meter Compact Flow Meter for Low Flow Rates ■ Liquid flow rates up to 40 ml/min ■ High chemical compatibility Product Summary The LS32-1500 enables precise, non-invasive measurements of dynamic liquid flow rates up to 40 ml/min bi-directionally. Excellent biocompatibility is ensured by the exclusive use of high-performance stainless steel, PTFE and PEEK for the wetted parts. The flow path of the LS32-1500 liquid flow sensor is formed by an especially thin-walled, straight tube which assures excellent sensitivity. Interface Options Digital - I2C-Bus For more information on communication, please refer to page 2 of this document. 1 Sensing Performance Table 1: Performance of LS32-1500 (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 specification between full scale and saturation point. bAccuracy respectively repeatability below ±20 ml/min.
