MTF variable area flow meter for micro flow can measure tiny liquid or gas, which has the characteristics of stable and reliable measurement and wide application range. The instrument is equipped with a fine-tuning valve to facilitate the user’s setting of a specific flow rate. Instrument is based on the float measurement principle. According to the flow direction of the medium, it can be divided into side in and out, bottom in and out of two types. According to the display mode, it is divided into mechanical pointer type and liquid crystal display with 4-20 mA current output type.

MTF Micro Flow Variable Flow Meter can measure the micro flow of liquid or gas, with stable and reliable measurement and wide range of applications. This instrument can be widely used in petrochemical, oil refining, fertilizer, iron and steel, pharmaceutical and other industries for micro flow measurement, pipeline purging and process control.
MTF type micro flow variable area flow meter is divided into two structural forms: one is 10C type, suitable for low, fluid and high pressure, instrument range is 1-20 L/h (20℃ water), the transmitter can be MTF-A/M TF-B / MTF-TF-C/M TF-D type; the other is 10S type, suitable for low pressure, flow measurement range is 4-120 L/h (20℃ water), the transmitter can be MTF-A/M TF-B type, the instrument is equipped with fine tuning valve, convenient for users to set the specific flow.
Operating Principle
The measuring device includes a measuring tube in which the float can move freely up and down, the medium is bottom up through the measuring tube, the float self-adjusts to make the buoyancy A, pressure W and the float gravity G equal, namely G=A + W.
For the mechanical pointer display type, the measured flow rate corresponds to the position of the float in the measuring cone tube. Display the flow rate on the dial through the magnetic coupling structure. For the digital display type, the measured flow rate corresponds to the position of the float in the measuring cone tube, through the circuit conversion, and the 4-20 mA signal can be output.
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.It can measure liquid, gas and vapor (minimum measurable flow is 0.3L/h), especially for the flow measurement with small flow rate and low Reynolds number, it has more unique advantages than other flow meters.
7.Max pressure is 69Mpa
