Ultrasonic Doppler Flow Meter

Description

SUPMEA SUP‑FSD300 Ultrasonic Doppler Flow Meter

The SUPMEA SUP‑FSD300 Ultrasonic Doppler Flow Meter is a high-performance instrument designed to measure flow rate, liquid level, and temperature in natural waters, channels, pipelines, and other complex environments.
With its robust design, reliable accuracy, and non-invasive measurement approach, it is an ideal solution for applications where sediment, floating debris, or ice make traditional flow meters unreliable

Characteristics

Features

*High measurement accuracy, wide range, can measure weak flow or strong flow.

*Sensitive sensing, high resolution, not limited by the starting flow rate.

*Response speed is fast, can measure instantaneous flow rate, also can measure the average flow rate.

*Measurement linearity, there is no correction curve K, C value.
