Ultrasonic Flow Meters − Time of Flight and Doppler

The DFM2 is a microprocessor-controlled flow meter for the measurement and control of liquids flowing through process and effluent pipelines using the non-intrusive Doppler principle. The flow meter display indicates flow rate and total volume for a wide range of liquids, including aerated water, liquids containing suspended solids, slurries and sludges. The Safsonic DFM2 requires fluids with a minimum concentration of 100 ppm of solids or bubbles having minimum size of 100 microns. The unit has a 4-20mA output for flow rate, a pulse output for flow total and relay outputs

The PDFM3-L is a handheld non-invasive microprocessor based meter for measuring the flow rate and total volume of liquids flowing through process and effluent pipelines. It is suitable for a wide range of liquids, including aerated water, liquids containing suspended solids, slurries and sludges. The PDFM3-L requires fluids with a minimum concentration of 100 ppm of solids or bubbles having minimum size of 100 microns. The unit is fitted with a built in pulse logger and is supplied with a carry case, charger, batteries and all the necessary accessories.
