What flow meter is used to measure compressed air? There are various instruments that can be used to measure air, but the actual air flow rate used on site is not diverse according to their principles. The most important ones are rotor flow meters, throttling differential pressure flow meters, vortex flow meters, and averaging tube flow meters.
1、 When measuring compressed air, flow meters are usually installed in compressor rooms and blower rooms, and the vibrations generated by the compressor and blower will be transmitted to distant places through air pipes or ducts. Vibration causes the vortex flow sensor to generate interference signals corresponding to the same vibration frequency, resulting in significantly higher flow readings.
2、 Compressed air is taken from the atmosphere, which always contains a certain amount of water vapor. A larger orifice flow meter with a good four diameter orifice plate is used to measure the flow rate of compressed air. There is often water accumulation in front of the orifice plate, which affects the measurement accuracy. There is often a section of water in the pressure pipe, which causes the differential pressure measured by the differential pressure transmitter to be inconsistent with the differential pressure generated by the throttling device. These are common reasons for errors caused by air carrying water.
3、 The fluid at the outlet of compressors and blowers mostly contains some pulsation. Fluid pulsation can cause high readings in various flow meters such as differential pressure flow meters, vortex street flow meters, etc., leading to rotor jumping up and down in rotor flow meters. In order to eliminate the influence of pulsation, a buffer tank is usu
4、 The average speed high flow tube flowmeter has its unique advantages in measuring large caliber air flow, such as low price, simple and reliable, and easy installation and maintenance. It is a supplement to vortex flowmeters and throttling differential pressure flowmeters.
2... CSs latest research and development achievement - CMM 500 Powerbar flowmeter for compressor efficiency testing
CMM 500 Power Bar Flow Meter: The latest research and development achievement of German CS, the powerful tool for compressor efficiency testing. CMM 500 is a new reference flow meter developed by German CS Instrument Company specifically for high-precision measurement of compressor capacity and compressed air billing.. This flowmeter not only complies with the ISO1217 standard, but is also one of the most practical Venturi nozzle flowmeters currently on the market.
1. Product Features: The CMM 500 flowmeter has a super large measurement range of over 1:130, which means it can provide accurate measurement results under a wide range of flow conditions.
. Within the flow range of 0.2Qmax to Qmax with ultra-high precision, the measurement error of CMM 500 is less than 0.5%, ensuring high-precision measurement. This is crucial for applications that require accurate control of compressed air consumption. Easy to maintain, even during operation under pressure, CMM 500 can be repaired or maintained through mounting plates, including zero point calibration, condensate drainage, and sensor replacement for calibration.
