1. What is the appropriate diameter for an air compressor with a pressure of 0.65mpa and a flow rate of 40m ³/min? The flow rate on the nameplate of the air compressor should be based on the standard condition. If you want to install the TGF450 thermal gas mass flowmeter, it is recommended to use a DN125 pipeline; If you are installing a vortex flowmeter, you need to convert the standard condition into the operating condition, which can be done using the gas state equation. After converting the volumetric flow rate into the operating condition, according to V=Q * 354/D/Peng Chun D (V-m/s, Q-m ³/h, D-mm), the selection of DN80 caliber can be determined for compatibility and compatibility. Hefei Kemeijie - flow meter expert, pleased to answer your questions. 2. What is the fee standard for gas flowmeter calibration?
The fee standard for gas flowmeter calibration is determined based on factors such as flowmeter type, pipe diameter, accuracy level, and medium pressure. The specific cost ranges from several hundred yuan to tens of thousands of yuan.
. 1. Common gas flowmeter calibration fee standards: The following are the calibration fees for common types of gas flowmeters under specific conditions: • Gas turbine flowmeter: diameter DN>100mm, accuracy level 1.0 or below, charged 1950 yuan. Gas vortex flowmeter: with a diameter DN greater than 100mm and an accuracy level of 1.0 or below, the fee is 1950 yuan. Gas vortex flowmeter: - Diameter DN ＜ 100mm, accuracy level 1.0 or below, charge 750 yuan. -Diameter DN>100mm, accuracy level 1.0 or below, charge 1950 yuan. Gas ultrasonic flowmeter (pipeline type): with a diameter DN of (10-300) mm and an accuracy level of 1.0 or below, the fee is 2000 yuan. • Gas
3. Important note: The above charging standards are reference cases, and the actual cost may vary depending on the sending area and testing institution.
And the specific technical parameters of the flowmeter vary. The most accurate approach is to directly contact your local metrological verification institution (such as provincial or municipal metrology institutes, institutes, or qualified third-party testing companies), provide detailed model and technical parameters of the flowmeter, and obtain an official quotation. Do you know the measurement range of vortex flowmeter?
The measurement range of vortex flowmeter is relatively wide and can be applied to flow measurement of various liquids and gases. However, the specific measurement range may vary due to factors such as measurement medium, pipe diameter, and environmental conditions. The following is a detailed introduction: Industrial water full tube vortex flowmeter is mainly used for flow measurement of small and medium pipe diameters, while plug-in vortex flowmeter can be used for flow measurement of large pipe diameter (DN ≥ 300mm) pipelines..
