To insure acurate control of water treatment or for automation of chemical product metering or to insure that you comply with all regulations involved, flowmeters from Krohne, Greyline, American Sigma and Hach are good choices.

Greyline OCF-IV ultrasonic Flow Monitor is widely used for monitoring flow in open channels, upstream or downstream from municipal and industrial wastewater treatment plants.

The Stingray Level-Velocity Logger is a compact, battery-powered losser with an ultrasonic sensor. It is an essential tool for flow surveys in open channels, partially full sewer pipes and surcharged pipes.Finally, the PDFM-4 Doppler Flow Meter uses the Doppler ultrasound effect to measure flow from outside the pipe.

The 950AV Optiflo Flow Meter from American Sigma for open channels or pipes is the most multi-purpose of our flow meters for wastewater. It is portable and water-tight and accommodates 3 types of sensors for flow and level measurement, on top of probes for pH, conductivity, dissolved oxygen and temperature. Its datalogger also records data from other instruments.

Whether the pipe is partially or completely filled, Krohne's Tidalflux electromagnetic flowmeter always measures volume with accuracy. Capacitive and non-contact flow-level measuring system built into the wall of the measuring tube provides accurate flow measurements. The Optiflux 4000 electromagnetic flowmeter for filled pipeline with Teflon liner is the specialist of tough processes: wastewater, sludge, chemical products, corrosive or abrasive products, it can take them all.

Krohne's electromagnetic flowmeter with auto-diagnostic Optiflux is designed to resist abrasion and corrosion in all applications, from clean water to sludge and chemicals. Furthermore, the new Waterflux is the only electromagnetic flowmeter to offer battery autonomy of at least 10 years. To measure flow of clean water or non-conductive liquids such as ultrapure water, the ultrasonic flowmeter Optisonic based on Transit Time technology will bring you precision and reliability.

The Optimass Coriolis Mass Flowmeters, with single or double z shaped or straight tube, will be your first choice for tough applications to measure flow and concentration of chemical products or viscous and non-homogeneous liquids.

For all measuring applications of clean water flow, the six blade Paddle Wheel type probe from Hach is accurate and easy to use. A single controller can accomodate up to four probes.

Greyline's Transit Time-ultrasonic portable flowmeter is recommended for most clean liquids. Portaflow ultrasonic sensor straps-on the outside of pipes.
