Reasons for the high or low reading of the gas flow meter
Thread Content
The throttling element of a gas flow meter, also known as a differential pressure flow meter, consists of a primary sensing element (throttling element) and a secondary unit (differential pressure transmitter and flow display instrument), and is widely used for measuring gases. Flow measurement of steam and liquids. It features a simple structure, easy maintenance, stable performance, and reliable operation. Regarding the measurement performance of gas flow meters, the technical specialist from the manufacturer will explain below what the reasons are for either higher or lower measurement values. 1. Reasons for higher values: (1) The gas flow meter experiences significant pulses in flow rate. Exclusion method: Reduce the flow pulses in the pipeline. (2) The viscosity of the medium is too high. Exclusion method: Update and adjust the gears, then make corrections. 2. Reasons for the low value: (1) The actual flow rate measured by the gas flow meter exceeds the specified range. Exclusion method: Replace the flow meter with another specification or keep the operating flow within the specified range. (2) The medium viscosity of the gas flow meter is too low. Exclusion method: Replace the adjustment gear to make the correction. (3) The drive mechanism is inflexible or the rotor is in contact with the housing. Exclusion methods: Check whether the rotor, bearings, drive gears, etc. are installed correctly, and replace worn parts. At present, our company is looking forward to the future with optimism, working hard to build a solid foundation, keeping up with the times, and operating in good faith.

Gas is a rather special substance. Some have a high viscosity, which causes them to stick to the throttling elements and affects the measurements. Some have significant density changes affected by temperature, which can also cause problems with measurement. Furthermore, the gas components will change. All of these will affect the measurement.
(2) The medium viscosity of the gas flow meter is too low. Exclusion method: Replace the adjustment gear to make the correction. (3) The drive mechanism is inflexible or the rotor is in contact with the housing. Exclusion methods: Check whether the rotor, bearings, drive gears, etc. are installed correctly, and replace worn parts. Are there adjustment gears inside the orifice plate flow meter? Is there a rotor? Are there bearings? Sis, you’re really too sincere. Sales also requires learning *skills.

Gas is used in many turbines, right? The differential pressure itself has low precision, with large errors
