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.
1. High accuracy, good
stability, excellent repeatability. Measuring
tolerance: +/-0.5F.S; Long-term stability: +/-0.1%F.S/Y.
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.
± 0.2% F.S / Y
All kinds of liquid, gas and steam

Wedge-shaped flowmeteris widely used in the fields of petroleum, chemical industry, steel, light industry, sewage processing, environmental protection, water conservancy project and pharmacy to measure the volume flow of the conducted liquid mediums.
