Non-contact flow metering for dirty water
Easy to install and set up, with a single clamp-on sensor
Two million-point datalogger option
The meter does not make contact with the moving fluid and does not require any pipe cutting or drilling. It measures flow by reflecting an acoustic signal back to the sensor from particles or gas bubbles in the fluid. Installation is easy—just mount the strap-on sensor on the outside of a plastic or metal pipe. There’s no need to shut down your flow system.
Easy 5-button programming gets you up and running quickly. The meter features a white, backlit display with a 5-key keypad. This menu-driven flowmeter is easy to operate—you can even select English or Spanish directions.
Use the isolated 4-20 mA output signal to transmit flow data to remote displays, recorders or controllers. Use the two programmable relays for flow control, pump protection or flow proportional pulse. The flowmeter can measure reverse flow—a minus sign appears on the display during reverse flow conditions. The 4-20 mA signal, relays and totalizer are also configurable for reverse flow. Noise suppression circuitry filters "dirty" power and electrical interference from most VFD’s. Terminals are easily removable for electrical connections.
Choose from standard or datalogging units. Datalogging units log up to 2,000,000 data points that you can output via the USB port to a flash or thumb drive in the field. Datalogging units are independent of calibration units.
