Open Channel Flow Meters
You can buy and hire flow meters from our extensive range of products to measure flow in all open channel applications. We provide ultrasonic flow meters for weir tank and flume applications, area velocity flow meters for large open channel and in-pipe applications and bubbler flow meters for difficult industrial effluents.
Flow instruments integrate with our other technologies including automatic samplers and water quality montioring equipment to satisfy a range of challenging applications.

Isco 2150 Doppler Area Velocity Flow Meter
The Isco 2150 is part of a modular, stackable solution for open channel flow applications. A continuous wave Doppler flow sensor measures velocities in the flow field. A differential pressure transducer in the sensor measures depth. From this, average velocity and flow rate is automatically calculated at the required measurement interval. The Isco 2150 is suitable for permanent and portable applications.

Isco 2150EX Explosion Proof Doppler Flow Meter
The Isco 2150EX is part of a modular, stackable solution for flow measurements in hazardous environments; ATEX certified for use in Hazardous Zones 0, 1 and 2. It is used extensively in sewer flow surveys but can also be used in permanent installations. A continuous wave Doppler sensor measures velocities in the flow field. A differential pressure transducer in the sensor measures depth. From this, average velocity and flow rate is automatically calculated at the required measurement interval.

Isco ADFM Pro20 Flow Meter for Large Channels
The Isco ADFM Pro20 measures flow rate to within 2% of actual value, in flow depths up to 6.5 metres. It brings accurate flow rate measurement to a traditionally difficult measurement environment; large pipes and open channels. The ADFM (Acoustic Doppler Flow Meter) uses Pulse-Doppler velocity profiling technology to measure the velocity distribution within the flow. It is of particular use at those sites with non-uniform, rapidly changing, near zero, zero, or reverse flow conditions.

Isco 4200 Series Flow Meters for Fixed Sites
No single technology is suitable for all open channel flow measurement applications. The Isco 4200 Series provides a choice of technologies including ultrasonic, bulbbler and area velocity to suit each particular application. The Isco 4200 series flow meters are designed for fixed sites primarily for trade effluent and sewage treatment works. Each flow meter integrates easily and flexibly with Isco automatic samplers, and has add-on modules for pH/temperature, and DO/temperature to provide a complete effluent monitoring solution.

Isco 4210 Ultrasonic Flow Meter
The Isco 4210 Ultrasonic Flow Meter is ideal for flow measurement applications in weir tanks and flumes. As the sensor is mounted above the flow stream it is not affected by chemicals, high concentrations of grease, suspended solids or silt. The Isco 4210 integrates easily and flexibly with Isco automatic samplers, and has add-on modules for pH/temperature, and DO/temperature to provide a complete effluent monitoring solution.

Isco 4230 Bubbler Flow Meter
The Isco 4230 Bubbler Flow Meter provides accurate measurement in a variety of conditions. It is not affected by wind, steam, foam or turbulence and because only the bubble tube contacts the flow, corrosive chemicals are not a problem. The Isco 4230 integrates easily and flexibly with Isco automatic samplers, and has add-on modules for pH/temperature, and DO/temperature to provide a complete effluent monitoring solution.

Isco 4250 Area Velocity Flow Meter
The Isco 4250 Area Velocity Flow Meter is ideal for sites where weirs or flumes are not practical and submerged, surcharged, full pipe or reverse flow conditions may occur. The Isco 4250 sensor is mounted at the bottom of the channel and uses Doppler technology to directly measure velocity throughout the flow stream. An integral pressure transducer measures depth to determine flow area. The Isco 4250 calculates flow rate by multiplying the area of the flow stream by the average velocity.
