Product Instructions


Wedge-shaped flowmeter is new style differential pressure flow instrument of our company, which is consist of flow sensor and differential pressure transmitter.  It has already made up the gap that domestic measuring domain have no flowmeter that can measure city gas with large-scale change(flow change can be dozens of times with the change of time) and natural gas; Which has solved the flow measuring difficulty of pix, pitch, residue oil, paraffinic oil and all kinds of mediums with high viscosity. Besides, it is also widely used in measuring those enterprises with strong causticity, those saturated or oversaturated acid, alkaline, and saline liquid will separate out crystallization with the change of temperature.


Product Features


1. High accuracy, good stability, excellent repeatability. Measuring    tolerance: +/-0.5F.S; Long-term stability: +/-0.1%F.S/Y.

2. Simple structure, reliable stability, long-term use, five-years maintenance-free.

3. Wide measuring range. Rate of measuring range normally is 1:25, can be 1:33. After changing the differential pressure, the rate can be more than1:100.

4. Less requirement on straight pipe installation. Can effectively avoid the uncertainty of additional measure.

5. Less pressure loss, saving resource.
