Smart Ultrasonic Meter Meets Diverse Open-Channel Flow-Measurement Requirements

Open channels are a cost-effective solution for managing varying flow rates in unpressurized systems. However, flow through open channels cannot be measured by many common flow measurement technologies, and converting to a closed, full-pipe system can be costly and too restrictive for large flow events.

The Dynasonics iSonic 4000 flowmeter from Badger Meter is well suited for applications ranging from flow into water treatment plants, storm and sanitary sewer systems, and effluent from water resource recovery, to industrial discharge and irrigation channels.

It employs a noncontact ultrasonic level sensor to measure the water level in a flume, weir or other channel. The unit is programmed using three front-panel push buttons, with the programming menu offering a wide variety of primary flow elements.

Cost-Effective Measurements

Based on Manning’s equation, the flow rate is determined according to the dimensions, characteristics and water level of the channel. This correspondence between water level and flow rate allows for a cost-effective solution for measuring flow in angular open channels and partially filled pipes, as well as measuring volumetric contents of liquids in tanks.

“The iSonic 4000 is an intelligent and versatile ultrasonic meter/controller designed to meet a host of open-channel flow measurement requirements,” says Cheryl Ades Anspach, marketing manager of Badger Meter. “Its unique features and IP67 rating enable reliable performance in challenging outdoor environments. The meter is an effective tool for influent and effluent measurement, flow control and data logging.”

Interfacing Made Easy

The iSonic 4000 open-channel flowmeter easily interfaces with most SCADA systems. Simple to install and setup, it sends level, flow rate and total volume information over Modbus RTU. A robust data-logging feature 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° F (-20° to 60° C), the iSonic 4000 can be paired with the Badger Meter BEACON Advanced Metering Analytics software and AquaCUE Flow Measurement Manager system for use in utilities and water resource management.

Although the device normally functions as a flowmeter, it can be used for pump control based on the water level to reduce equipment costs. A rugged powder-coated aluminum enclosure protects internal components and extends asset life.

Badger Meter is an innovator in flow measurement, control products, and communications solutions, serving water utilities, municipalities, and commercial and industrial customers worldwide. The company’s products measure water, oil, chemicals, and other fluids, and are known for accuracy, long-lasting durability and for providing valuable and timely measurement data.
