A. Description of product:
Wedge flowmeter system is my company's latest development of a new generation of differential pressure flow meter system, it can satisfy the measurement requirements of most of the fluid, such as cleaning liquid, gas, steam, etc.It is especially suitable for measuring the traditional fluid flow meter is hard to measure, such as pulp, pulp, slurry oil, fuel oil, residual oil, coal tar, and other high viscosity fluid and suspension, easy to crystallization, smudgy fluid.Therefore, wedge flowmeter system is widely used in petroleum, chemical, power, light industry and other fields with high viscosity and low Reynolds number of medium measure
Second, instrument features
« the "V" type throttle body parts can eliminate the retention area, to prevent the occurrence of congestion in system.
« yes applicability is wide and Reynolds number when Reynolds number is 500, remains the differential relation with the square of the flow.
« use of installation and maintenance is convenient.
« measurement precision is high, the expanded uncertainty flow calibration: plus or minus 0.5% to plus or minus 0.2% school school or oil (water).
« long-term stability is good, by the user as the zero meter failure rate.
« a table separation, replace the wedge (middle) can be extended range.
The « diverse styles:
Normal: range than in the "scope, flow coefficient of the nonlinear error of plus or minus 1% or less.
High performance type: range than in 1:3, the expanded uncertainty range flow calibration is plus or minus 0.5% ~ + 0.2%.
« set overpressure alarm values according to the situation of pressure and low pressure alarm value, when using in overpressure or low pressure instrument sound and light alarm automatically, prevent caused by overpressure of production safety accidents.
