The DFM2 is a microprocessor-controlled flowmeter for the measurement and control of liquids flowing through process and effluent pipelines using the non-intrusive Doppler principle. The flowmeter display indicates flow rate and total volume for a wide range of liquids, including aerated water, liquids containing suspended solids, slurries and sludges. The Flowmetrix 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 and a pulse output for flow total.
The Doppler Flow Meter - DFM2 measures the velocity of fluids in pipelines using a totally non-intrusive principle. The DMF2 utilises a high speed, 16-bit microprocessor unit with 32-K byte FLASH memory. The user-friendly flowmeter comes with a range of features to ensure easy and reliable flow measurement. The flow signal from the flow sensor is continuously analysed and should the signal quality become unacceptable an error message is displayed.
Standard features include an isolated 4 – 20mA output signal, an isolated pulse output and a relay output.
It is designed for use with sewage, waste water, pulp stock, mining slurries, food products and other fluids which contain in excess of 0,1% suspended solids or bubbles. The particle size for successful operation must be greater than 100 microns.
Available configurations
The DFM2 sensor cable is 3 metres in length. The model DFM2-1 is designed to accept the flow signal directly from the sensor, and the flowmeter must be mounted within 3 metres from the sensor. The model DFM2-2 is supplied with an in-line amplifier. The 3 metre sensor cable is supplied connected to the in-line amplifier, and a is used to connect the in-line amplifier to the flowmeter.
