01Overview

Engineered for the field

A non-contact radar flow meter for open channels, rivers and canals. Mounted above the water, it measures surface velocity with 24 GHz radar from 0.1 to 20 m/s (±2%) and water level from 0.1 to 20 m (±1 mm), then calculates the mean cross-section velocity and flow rate from the channel profile. Because nothing touches the water, the sensor is unaffected by silt, debris or corrosive sewage and needs no excavation or in-stream structures. The IP67 housing operates from -40 to +80 °C, and data is output over RS485, ready for connection to an RTU or data logger.

02Key Features

What makes the HYD-190 different

01

Non-contact measurement

Mounted above the water, so silt, debris and corrosive sewage never touch the sensor.

02

Velocity and level in one

Measures surface velocity and water level from a single device.

03

Automatic flow calculation

Combines mean velocity with the channel cross-section to report flow rate.

04

Rugged IP67 build

Operates from -40 to +80 °C for year-round outdoor installation.
