Sensirion LD20-2600B Liquid Flow Sensor

Sensirion LD20-2600B Liquid Flow Sensor is designed to measure dynamic liquid flow rates from a few hundred μl/h up to 1000ml/h bi-directionally. This single-use high-performance liquid sensor is built on the CMOSens® technology. The LD20-2600B sensor includes linearized, temperature-compensated, and fully calibrated digital output signals (I2C). This liquid flow sensor features 5% accuracy (H2O), 0.5% repeatability (H2O), 6000μA maximum supply current, and a straight, unobstructed flow channel without moving parts. Typical applications include advanced infusion therapy, biopharmaceutical processes, portable drug delivery devices, and home care.

The LD20 base station is used to evaluate and test the LD20-2600B liquid flow sensor. The connector block mechanically holds the sensor in place through a clip-in mechanism and provides an electrical interface between the contact pads of the sensor and a PC.

The POGO-PIN is a spring-loaded test probe can be used with the LD20-2600B liquid flow sensor and LD20BASESTATION.
