      MTF Variable Area Flow Meter (Rotameter)

      MTF variable area flow meter is measured by outputting 4~20 mA two-wire linear current signal, and the communication protocol is loaded. The remote configuration, monitoring, maintenance and calibration of the instrument can be realized. The pressure regulator (constant flow valve) can be selected to make the outlet flow stable.

      Features

        1.It can measure liquid, gas and vapor, especially for the flow measurement with small flow rate and low Reynolds number, it has more unique advantages than other flow meters.
        2.Lower pressure loss, generally is 4~9kpa, higher is 20kpa.
        3.There is a wide flow range, generally is 10:1, the special design flow range can be extended.
        4.The factory calibration adopts the method of 11 sections calibration, and the precision of the product reaches 1.0 grade.
        5.It can select card sleeve connection, piping φ6mm、φ8mm、φ10mm、φ12mm. Flange connections can also be selected and the flange standard is determined according to user requirements.
        6.Max pressure is 69Mpa
