LGXS Wedge Flow meter has been widely used in recent years. It has been widely used in foreign petroleum, chemical and other industries. The flow rate and differential pressure remain root relationship at a very wide Reynolds number range. Wedge Flow meter is very suitable for low Reynolds number fluid flow measurement, especially in the measurement of high viscosity fluid, containing solid particles, slurry fluid, has more advantages than other throttling devices.
Operating Principle
Basic principle of LGXS wedge flow meter also comes from conservation of energy and continuous equation, putting the wedge whose longitudinal section is triangle into process pipe, when the fluid flows through the wedge flow meter, due to the throttling effect of the wedge, a differential pressure is generated on the upper and lower sides of the wedge, which is squared with the volume flow rate, the differential pressure transmitter can output the standard signal which is square relation with the measured fluid flow value, and then the flow value can be obtained.
Features
1.Wide viscosity range, the flow rate and differential pressure can maintain a root relationship in the range of Reynolds number from 500 to millions.
2.High accuracy, the basic error of the calibrated wedge flow meter is within ±0.5%.
3.Self-cleaning ability, no stagnant area.
4.Good wear resistance.
5.Permanent pressure loss is smaller than orifice plate.
6.Good repeatability and high reliability.
7.Long life, low cost, easy installation and maintenance.
8.Bidirectional flow measurement. Minimum straight pipe section requirements: upstream 5 times of pipe diameter, downstream 2 times of pipe diameter.
9.Repeatability : ±0.2%.
