How to maintain the accuracy of rotary gas flow meters? Posted by : admin / Posted on : Oct 14， 2022

The principle of measuring the flow of a gas is simple, but the actual process is complicated. The device has to measure both low and high flows with great accuracy and sensitivity. It must be compatible with the size and environment of the process, and it must be durable to withstand any hazards that it may encounter. It should also be calibrated to the actual process conditions, since this ensures undisturbed operation.

The Diaphragm of gas flowmeter works by using a pressure sensitive diaphragm to measure gas flow rates. This type of meter is generally able to work with gases up to 0.5 bar and flows up to 160 m3/hr. These meters can also be equipped with a pulse generator. These pulses are then recorded on a data logger and are converted into readable data. The data from these meters is then sent to an automated reading system (AMR). This system is designed to collect data from a variety of meters and can help to detect tampering and unusual usage.

The rotary gas flowmeter is an instrument that measures the amount of gas passing through it. It is equipped with a high precision mechanical index. It is also suitable for use in tight spaces. The meter is also designed with a robust casing made of high-strength aluminum alloy. The material used to manufacture the casing increases its wall thickness and ensures long-term stability of the system. Moreover, the meter's surface seal improves its sealing performance and extends its operating range.

To maintain the accuracy of your rotary gas flowmeter, it is important to periodically check the oil level of the device. The time between these checks will depend on your requirements and the quality of the gas. Moreover, it is important to replace the oil when it becomes discolored or emulsified. In addition to visual inspection, you should also conduct a differential rate test to compare the performance of the device.
