Venturi tube flowmeter
Venturi tube (Venturi tube) is divided into built-in venturi tube and plug-in venturi tube according to the structure. Good results have been obtained in the measurement of combustion-supporting air, cold air, and gas metering (blast furnace gas, coke oven gas, converter gas) of hot blast stoves in iron and steel plants, and large pipe diameters and low flow rate pipe meters of boiler primary air and secondary air in thermal power plants. Solve the problem of accurate measurement of various gas flows in current industrial enterprises in low pressure, large pipe diameter, and low flow rate. A fluid measuring device with a wide measuring range and easy installation. The unique structure design and data processing method have strict fluid mechanics basis, and the real flow calibration is carried out in the national large-scale key wind tunnel laboratory.
can be used for the control and measurement of large-diameter fluids in the petroleum, chemical, metallurgical, electric power and other industries.
(1) The resistance to the fluid is small, about 150Pa, so the energy consumption is low.
(2) The pressure difference is large, the accuracy is high, and the measurement range is wide.
(3) Good stability and smooth pressure difference characteristics.
(4) It has a wide range of applications, such as general gas, flue gas, blast furnace gas containing more impurities, etc., without clogging after long-term use.
(5) Easy installation and long-term maintenance.
