I. Overview:

Wedge-shaped flowmeter is a flow meter with a V-shaped throttling element for flow measurement. It has a rounded top Angle facing down, which is conducive to the smooth passage of liquid containing suspended particles or viscous liquid, and does not produce stagnation upstream of the throttle. The wedge flowmeter can be used to measure the flow of viscous liquid. Viscosity can be as high as 500mPaS, used for slurry, slurry, sand crude oil, sewage, heavy oil, residue and other solid containing suspension and low Reynolds number liquid media flow measurement, can also be used for gas, steam medium flow. The product is used for all kinds of gas, especially for the flow measurement of dirty gas and natural gas.

Ii. Characteristics:

1, the use of "V" type body throttling parts can eliminate the retention area, prevent the system blockage phenomenon.

2. Reynolds number has a wide range of application. When Reynolds number is 500, the square relationship between differential pressure and flow rate is still maintained.

3, differential pressure transmitter can output 4 ~ 20mA electrical signal, easy to use a variety of instruments.

4. Easy installation, use and maintenance.

5, high measurement accuracy, flow calibration expansion uncertainty: ± 0.5% ~ ± 0.2% (water calibration or oil calibration).

6, good long-term stability, praised by users as zero failure rate instrument.

7, a table split, replace the wedge (middle) can expand the range.

8. Various styles:

Common type: range ratio in the range of 1:5, the nonlinear error of the flow coefficient is ≤± 1%.

High performance model: The extended uncertainty of flow calibration is ± 0.5% ~ ± 0.2% in the range ratio of 1:30.
