PRODUCT OVERVIEW

Ultrasonic Doppler Flowmeter

A high-performance fixed flow measurement device designed to measure water velocity and water level for calculating flow rate in a given section.

MiniOFS Optical Fog Sensor
Advanced sensing for reliable flow measurement.

The ultrasonic Doppler flowmeter sensor is a high-performance fixed flow measurement device. Its fundamental principle involves measuring flow velocity and water level (cross-sectional area) to calculate the flow rate of the water in a given section.

The sensor uses optical measurement technology to detect changes in atmospheric visibility and provides reliable visibility information for monitoring and warning systems.
