Badger Meter introduced the Dynasonics iSonic 4000 flow meter at the WEFTEC conference in Chicago. The device aims to provide an economical solution for a wide range of open-channel flow measurement applications.

The meter accurately measures the level, flow rate and total volume of water flowing through weirs and flumes. Open channels are often used to manage varying flow rates in unpressurized systems, but the flow through such channels can be challenging to measure with commonly used meters, and converting from a channel to a closed, full-pipe system can be costly and too restrictive for large flow events.

The Dynasonics iSonic 4000 flow meter suits applications including flows into and out of water and wastewater treatment plants, storm and sanitary sewer flows, and industrial discharge flows. It uses a noncontact ultrasonic level sensor to measure the water level in a flume, weir or other channel.

The device is programmed with three front-panel pushbuttons, while the menu offers a wide variety of primary flow elements. The flow rate is determined by the dimensions, characteristics and water level of the channel. The correspondence between water level and flow rate allows for a cost-effective solution for measuring flow in angular open channels and partially filled pipes, and for measuring the volumetric contents of liquids in tanks.

The device has an IP67 rating for reliable performance in challenging outdoor environments. It interfaces with most SCADA systems and is simple to install and set up. It sends level, flow rate and total volume information over Modbus RTU. Robust data-logging with selectable intervals provides a backup of measurements in case of network outages or reporting lapses.

With an operating temperature range of -4 to 140 degree F, the unit can be paired with Badger Meter BEACON Advanced Metering Analytics software and the AquaCUE flow measurement manager system. Although the device normally functions as a flow meter, it can be used for pump control based on the water level to reduce equipment costs. A powder-coated aluminum enclosure protects internal components and extends asset life. www.badgermeter.com
