Product Specification
Ultrasonic Flow Sensor
Part Number: US0014-001
Model Number: T/R975-US0014L353-01
Overview
The ultrasonic flow sensor is used as the core element of ultrasonic flow meters. Ultrasonic flow measurement uses the transit
time principle, whereby opposite sending and receiving ultrasonic flow sensors are used to transmit signals through the flow. The
signal travels faster when moving with the flow stream rather than against the flow stream. The difference between the two transit
times is used to calculate the flow rate.
