Multi-channel flow transmitter

The invention belongs to the technical field of fluid control, and provides a multi-channel flow transmitter which comprises a meter body, a connecting plate and a differential pressure transmitter. The differential pressure transmitter is arranged on the side face of the meter body, is connected with the meter body through the connecting plate and is used for detecting differential pressure whenfluid passes through a throttling orifice plate and converting the differential pressure into 4-20 mA analog signals or digital signals; the meter body comprises the throttling orifice plate, a middlepipe section and flanges at the two sides, the throttling orifice plate is arranged on the radial section of the middle pipe section, and a plurality of holes are evenly distributed in the throttlingorifice plate. If gas passes through the upper-layer holes, and if sediment passes through the lower-layer holes, the problems of gas-water diversion and sediment accumulation are effectively solved,and structurally, the two s
