The Signature® LaserFlow system uses a non-contact TIENet® laser Doppler sensor to measure liquid velocity beneath the surface. This sensor has an integral non-contact ultrasonic level sensor to measure liquid level. Flow rate and total flow data is then calculated from the measured liquid level and velocity which is then stored in flash memory.

Flowlink software (5.10.6 or newer) is recommended if data analysis and advanced reporting is required. This TIENet®-capable flow meter can be expanded with up to nine TIENet devices such as redundant measurement devices, water quality parameter sensors, sampler interfaces, and analog outputs.
