Open Channel Flowmeter
Open Channel Flowmeter
The common method of measuring flow through an open channel is to measure the height or HEAD of the liquid as it passes over an obstruction (a flume or weir) in the channel. The velocity of a river or stream can also be measured using spot velocity meters such as turbine or doppler ultrasonics. There are many types of open channel flow meters

Open Channel Flowmeter

The Mace FloSeries3 AgriFlo ultrasonic flow meter is a Doppler ultrasonic water meter that can measure flow practically anywhere - full pipes, partially-full pipes and open channels. You also have the ability to measure up to three flows with a single Mace FloSeries3 AgriFlo ultrasonic flow meter.

The Mace FloSeries3 AgriFlo ultrasonic flow meter features a UV stabilized poly carbonate enclosure material and an IP66 enclosure rating for outdoor installations. Solar power and telemetry options allows for remote monitoring. With the Mace FloSeries3 AgriFlo ultrasonic flow meter you also get a true average stream velocity measurement along with the ability to log flow rates and totals. The Mace FloSeries3 AgriFlo ultrasonic flow meter also features high accuracy and no moving parts.

The Mace FloSeries3 AgriFlo ultrasonic flow meter requires additional components for all applications. The sensors are not included with the AgriFlo and must be purchased separately along with any needed sensor mounting options. Additionally, the power supply and meter mounting kits are also available as accessories
