Wedge Shaped Flowmeter

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.
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. Wedge-shaped flow sensor
has special structure, differential pressure with excellent property, through serious test and correction, its life can
be ten years.
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.Immense application. Not only can be used for single-phase liquid, but also can be used for gas-liquid,
gas-solid and liquid-solid double-phase fluid. The minimum Reynolds number can be 300, maximum can be
1x107.
5.Anti-adhesive, no deposition, non-clogging. The measuring pipe of wedge-shaped sensor and the design of
anti-adhesive structure, prevent silt, powder, suspended solids and fiber from adhering and piling to the pipe of
sensor, and avoiding the corroding measuring pipe, thus ensure the long-term accuracy of measuring pipe.
