Open Channel Flow Measurement

Isco flow meters designed to monitor flow in challenging conditions for applications such as:
Wastewater treatment plants
Industrial pre-treatment
I&I and Billing
Surface water and Stormwater monitoring
CSO and SSO
Full pipe monitoring

No single measurement technology is suitable for all open channel flow monitoring applications. Only Isco offers you a choice of ultrasonic, submerged probe, bubbler, and area velocity flow meters.

LaserFlow™ Non-contact Velocity Sensor

The LaserFlow remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology. The sensor uses advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream.

The LaserFlow is ideal for a broad range of wastewater monitoring applications. It is compatible with both the Teledyne Isco Signature Flow Meter and the Teledyne Isco 2160 LaserFlow Module, depending on the type of installation.

ULTRASONIC OPEN CHANNEL FLOW MEASUREMENT

Ultra 3 and Ultra 5
Ultra 3 and 5 represent the leading edge of ultrasonic level measurement and control. Sophisticated, full function controllers with either 3 (Ultra 3) or 5 (Ultra 5) control/alarm relays and mA output. Wall, fascia, panel or rack mount, Ultra 3 and 5 units provide large displays with intuitive and straightforward menu programming. An Ultra system consists of a control unit and a transducer, which may be positioned up to 1,600 feet away. Both Ultra 3 and Ultra 5 have the option of bus type digital communications and data logging and, coupled with the dBMACH3 transducer which offers a virtual zero dead zone to 8.2 feet range.

ULTRASONIC OPEN CHANNEL FLOW IMMUNE TO SOLAR RADIATION

FlowCERT with DUET sensor
FlowCERT and DUET achieve the highest possible accuracy in open channel measurement and includes 5 control/alarm relays, mA output, plus data logging facilities. With the highly-accuracy temperature independent DUET transducer, which uses two transducers to dynamically compensates for any changes in the speed of sound between the transducers and liquid surface, making solar radiation issues a thing of the past. Typical accuracy is 0.02 inches.

ULTRASONIC OPEN CHANNEL FLOW, WHERE NO PMD EXISTS

FlowCERT with Speedy Velocity sensor
FlowCERT is a complete solution for high-accuracy measurement of open channel flows where no primary measurement device (PMD) exists. The FlowCERT offers 5 control/alarm relays, mA output and data logging facilities. Teamed with the Speedy Velocity sensor where it provides the velocity measurement for velocity x head calculations. The Speedy has a range of +/- 20ft/s and works in conjunction with either the dBMACH3 or DUET transducers.

Flow Hunter II and XDS 03 Transducer - Ultrasonic Open Channel Flowmeter

The Flow Hunter II provides non-contacting ultrasonic open channel flow measurement with the latest digital echo processing for superb performance. It can accurately measure to +/- 0.25% of measured range or 6 mm (whichever is greater).
