Is the nozzle type flowmeter the same as the cone type differential pressure flowmeter?

They are different. A nozzle flowmeter is a differential pressure generating device for measuring flow rate, which can be used in conjunction with various differential pressure gauges or transmitters to measure the flow rate of various fluids in pipelines. The standard spray nozzle throttling device is used in conjunction with a differential pressure transmitter to measure the flow rates of liquids, vapors, and gases. It is widely used in various combustion industries such as petroleum, chemical, metallurgical, power, and light industry. Cone flowmeter is a new type of differential pressure flow measurement device, which uses a unique edge wall gradually contracting throttling method to change almost all the disadvantages of conventional throttling devices. Clear width is a revolutionary achievement of differential pressure flowmeter. Its principle is the same as other differential pressure flow meters, which is the classic principle of energy conservation and flow continuity in closed pipelines, and has self rectification, self-cleaning, and self-protection functions.

2. Advantages of V-cone flowmeter

1. Advantages: (1) Uniform velocity effect on fluid, stable signal: "Signal fluctuation" is 1/10 of the orifice plate, so the req

Cone flowmeter
uired straight pipe section for installation is short, solving the problem of long straight pipe section for differential pressure instruments that has long troubled users (front 0-3D straight pipe section, back 0-1D straight pipe section) (2) High accuracy ± 0.5%, good repeatability ± 0.1%, wide range ratio 10:1

(3) Wear resistance, long-term stability and accuracy, no need for repeated calibration

(4), self-cleaning function.

The dirt flow will not block the body. For extremely dirty fluids, our companys independent intellectual property anti blocking patented technology has completely solved the problems of blockage and adhesion of throttling components and pressure pipes in blast furnaces and tar gas measurements.

(5)、 Sensors are metal bodies without electronic components, therefore they are resistant to high temperatures and vibrations.

(6)、 The applicable fluids are very wide, and both low and high flow rate fluids can be accurately measured. The specifications are complete and suitable for orange peel diameter estimation from DN15 to DN3000.

(7)、 Small pressure loss: with the same β value, the pressure loss is 1/3 to 1/5 of the orifice plate

(8). Flexible installation method: optional pipeline method, circular flange type, direct welding type, square tube type
