The wedge flometer is a new type of throttling differential pressure type, which can perform high-precision flow measurement in the case of high viscosity, low Reynolds number (Reynolds number> 500 can be used); Large diameter flow measurement occasions have unparalleled advantages and irreplaceable effects.
The wedge flometer has the function of correcting parameters such as flow coefficient, non-linear error, temperature change, density change, etc.; measurement accuracy can reach 0.5%; it can have on-site display and standard current signal (4-20mA DC) output, which can be conveniently used Automatic control system or network with computer for automatic adjustment and control of flow or other parameters.
Wedge flow meters are mainly used for high viscosity (heavy oil, residual oil, diesel oil, engine oil, etc.), industrial gas (coke oven gas, blast furnace gas, producer gas, city gas), hydrogen, nitrogen, air, water vapor, sewage liquid, etc. Flow measurement of the medium.
This kind of flometer has simple structure, no moving parts, is not easy to be worn by the fluid, stable and reliable working performance, and long service life; its measuring element and pressure taking device have a special structure, and the fluid will not be stagnated or blocked when the fluid passes, and the pressure loss is relatively high. Small, it is a good choice for high-precision flow measurement when the Reynolds number is low.
* Low Reynolds number measurement
* Low pressure loss
* Self-cleaning function
* High viscosity measurement (500, 1000, 3000 centipoise or higher)
* Wear-resistant and maintenance-free (no moving parts)
* Two-way flow measurement
* With minimum requirements for straight pipe sections (upstream 5 times the pipe diameter and downstream 2 times the pipe diameter)
* Wide size range: DN15-DN1200
* Optional wedge wear-resistant coating: in the coal slurry gasification process gasification, slag water treatment, etc., tungsten carbide spraying technology can be applied (the coating contains nickel, chromium, and boron alloys, which have stronger adhesion). Resist the impact of hard particle fluids such as black water and gray water.
* High turndown ratio: 10:1
