Mass Flow Meter

Mass Flow Meter


Model MFM-393 is micro-controller based arithmetical computation unit generally used in mass flow applications. The unit accepts three 4-20mA inputs at a time. Computed output is equal to, Square Root of (Input1) x (Input2) / (Input3) where, Input1 is Differential Pressure from D.P.Tx (Non Square Rooted) Input2 is Line pressure from Pressure Tx Input3 is Line Temperature from Temperature Tx Facility is provided to add gain and bias to each input and at the output stage. Gain and bias values will be entered from keyboard. MFM-393 displays instantaneous Mass Flow rate on 4 digit LED Display. Flow Rate and Totaliser range can be configured as required even at site. Totaliser is a 8 digit LED Display. Totaliser can be reset manually or REMOTE as optional. The unit incorporates two relays, from which one can be used for alarm for instantaneous flow & one for batch counter or both for alarm. On each set point one contact output is given, which can be used for control or hooter applications Power Supply for external transmitter (24 V DC @ 100 mA) is a standard feature. It eliminates need of separate power supply to power the transmitter. For batch counting, batch count can be set. When flow total equals preset count, system gives a contact output. It can be used for control operations like dosing, stoppage etc. Optional Relay output for 2 set points or Batching relay MFM 393 provides linear 4 - 20 mA retransmission signal corresponding to Calculated Mass Flow Rate for other panel mounted instruments like recorders, controllers etc. Serial connectivity on RS485 port with MODBUS RTU protocol Application 1) Steam Flow measurement for Boiler application 2) Fuel Flow measurements Petrochemical applications. 3) Accurate Flow Control Applications.
