The maximum temperature of the integrated orifice flowmeter does not exceed 100°. Even if the transmitter is below the orifice, the heat of the steam will be conducted. In this case, the differential pressure transmitter is firstly removed from the pressure guiding hole, the pressure guiding tube is lengthened, and a condensation tank is added to the positive and negative pressure taking ports of the orifice plate, and a three-valve valve group is added. Successfully tested. If it is in the north, there is a possibility that the instrument or pipeline may be frozen. Therefore, attention must be paid to the pipeline insulation and heat tracing to ensure the maximum service life of the product.

Integral orifice flowmeter structure:

1. Throttle parts: standard orifice plate, standard nozzle, long diameter nozzle, 1/4 round orifice plate, double orifice plate, eccentric orifice plate, round orifice plate, conical inlet orifice plate, etc. 2. Pressure device: ring Room, pressure flange, clamping ring, pressure tube, etc. 3, connection flange (national standards, various standards and other design departments of the flange), fasteners.

4. The measuring tube integrated orifice flowmeter is a high-range differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter, which can measure the flow of gas, steam, liquid and natural gas. It is widely used in petroleum. Process, chemical, metallurgy, electricity, heating, water supply and other areas of the process control and measurement.
