1. Product overview of Weiliba differential pressure flowmeter.
The Willylbar differential pressure flowmeter is a device that measures the flow rate by differential pressure and has been developed on the basis of the pitot tube flow rate measurement principle. It can measure the flow rate of liquids, gases, and vapors. With no moving parts, almost no pressure loss, easy installation and maintenance, and extremely low operating costs, it is favored by users.
The ALHLV Powerbar Differential Pressure Flowmeter is a highly accurate and reliable sensing element designed to be fully aerodynamically engineered and is suitable for high-precision flow measurement of gases, liquids and steam. The low-pressure hole of the ALHLV Williba differential pressure flowmeter is intrinsically anti-foulingGenerally, dust, sand and particles are concentrated at the rear of the probe under the action of vortex forces. That's why the leaves of the trees in autumn are always concentrated behind a leeward house. For other probes, the low-pressure pressure hole of the probe is quickly blocked by the impurities brought by the eddy current under the action of vortex force. The unique design of the Verabar flow meter allows the low-pressure pressure take-off holes to be located on both sides of the probe side, at the front of the fluid separation point and the wake zone. This design inherently prevents clogging and produces a very stable low-voltage signal. 
2. Product features of Weiliba differential pressure flowmeter:
1. High accuracy: in the range of 3% and 100%, the accuracy is 02%。
2. Energy saving: The primary measuring element Ba class sensor is made of 20 50 stainless steel, the cross-sectional area is very small, and there is almost no pressure loss in the medium pipeline, which greatly reduces the operating cost, and has obvious energy-saving effect compared with the orifice plate and other throttling devices.
3. Easy installation: only need to make a considerable hole in the appropriate position of the pipeline, and insert the primary element Ba flowmeter into the center of the pipeline, which can be easily installed.
4. No maintenance: the primary measuring element of the flowmeter itself does not need maintenance, only according to the regular verification requirements of the measuring instrument to the differential pressure transmitter for zero point and full inspection and the secondary meter input corresponding current for inspection.
5. Wide range of measurement flow: gas flow rate is above 4m s, liquid flow rate is 0Medium above 2m s can be accurately measured, and the measurement effect is especially good for low flow rate, small flow rate, and large pipe diameter.
6. Wide range of application of cross-sectional shape of medium pipeline: This flowmeter has no requirement for the geometric shape of the cross-section of medium pipeline, and is applicable to circular, oval, rectangular, square, prismatic, triangular, trapezoidal, etc.
7. High reliability: Because the structure of the Ba sensor is very simple, the structure design is reasonable, the medium in the impulse pipe does not flow, and the debris is not easy to enter, so it can maintain the measurement accuracy for a long time.
