Description
Wedge flowmeter is a new type of throttling differential pressure flow meter, which can be used in the case of high viscosity, low Reynolds number, Reynolds number, 500 can be used for high precision flow measurement.
Wedge flowmeter is a new type of throttle differential pressure flow measurement instrument, it can be used in the case of high viscosity, low Reynolds number, Reynolds number, 500 can be used for high precision flow measurement, in the flow of low flow rate, small flow, large diameter flow measurement occasions have unparalleled advantages and irreplaceable role. Wedge flowmeter is mainly used for high viscosity heavy oil, residual oil, diesel oil, oil, industrial gas, coke oven gas, blast furnace gas, producer gas, city gas, hydrogen, nitrogen, air, water steam, sewage liquid and other media flow measurement. The flowmeter has simple structure, no moving parts, is not easy to be worn by fluid, stable working performance, reliable, long service life. Its measuring element and pressure device structure Special fluid through the formation of no retention or clogging pressure loss is small is ideal for high precision flow measurement at low Reynolds numbers.
1 Good repeatability, high accuracy, calibrated wedge flowmeter, accuracy up to 0.5.
2 With self-cleaning ability, no stagnant area.
3 Wear resistance, long life, high reliability.
4 The permanent pressure loss is smaller than the hole plate.
5 One-type structure, no need to install the pressure guide pipe, directly connected with the pipe thread or flange. The construction saves time and labor and the maintenance is convenient.
Other features:
1) Suitable for measuring mud, coal tar pitch, coal water suspension and other high viscosity fluids;
2) At very low pipe Reynolds number (even as low as Re=500), the square root relationship between flow rate and differential pressure can still be maintained. The minimum Reynolds number of the orifice flowmeter is much larger than that of the wedge flowmeter.
3) The individually calibrated wedge flowmeter has a high measurement accuracy (up to 0.5%), and the accuracy of the uncalibrated wedge flowmeter can also reach about 3%;
4) Simple structure, easy installation, use and maintenance;
5) Can measure corrosive media, because the differential pressure measurement is the use of diaphragm type double flange differential pressure transmitter, corrosive media can not enter the pressure guide tube and differential pressure transmitter, so as long as the corrosion resistant material processing wedge throttle parts, you can make the instrument to measure corrosive media.
Product parameters:
1, measurement accuracy: ±1.0% ~ ±1.5%
2, the minimum flow rate: 0.01m/s.
3, service life: up to ten years or more.
4, range ratio ≥ 10:1
5, Reynolds number coefficient range: lower limit 300, upper limit up to 1×106 or more.
