What is the flow unit of a flowmeter? The flow unit of a flowmeter refers to the unit used to measure the flow rate of the medium measured by the flowmeter. The common flow units of flow meters are as follows: 1. cubic meter/hour (m ³/h): represents the volume of medium passing through the flow meter per hour
2. liter/hour (L/h): represents the volume of medium passing through the flow meter per hour, equal to 0.001 cubic meter/hour
3. kilogram/hour (kg/h): represents the mass of medium passing through the flow meter per hour
4. ton/hour (t/h): indicates the mass of medium passing through the flow meter per hour, equal to 1000 kilograms/hour
5. cubic meter/second (m ³/s): represents the volume of medium passing through the flow meter per second
6. liters per second (L/s): represents the volume of medium passing through the flowmeter per second, equal to 0.001 cubic meters per second
7. kilograms per second (kg/s): represents the mass of medium passing through the flowmeter per second
8. tons per second (t/s): The mass of the medium passing through the flow meter per second is equal to 1000 kilograms per second. The flow unit used by the flowmeter depends on the actual needs and the type of flowmeter. For example, for liquid media, cubic meters per hour or liters per hour are usually chosen as flow units; For gaseous media, cubic meters per second or liters per second are usually chosen as flow units. The selection and use of flow meters need to follow relevant industry standards and technical specifications to ensure the accuracy, reliability, and consistency of measurement results.

The

zero instability of mass flow meters is an important measurement indicator of Coriolis flow meters. Its main source is the sensor. Before the flow meter runs, there is a small time difference between the two detectors in the absence of logistics flow, which is the main factor of zero drift.

. Before the flowmeter is put into use, the Coriolis flowmeter needs to be zeroed, but after the zeroing is completed, there will still be residual deviation, which is caused by the original components of the flowmeter itself, and this deviation is called "zero instability". In general, it is a determined error value or error band. In general, the maximum allowable absolute error for the measurement of a Coriolis flowmeter is when the flow rate is greater than 20% of the range, and the impact on measurement accuracy is not significant; When the flow rate is below 10% of the range, the impact is significant; When the traffic is close to 0, the relative error is infinitely large. Analysis of the influence of gas content in oil on measurement accuracy: When oil contains gas, the vibrator will be affected. When the gas volume fraction is greater than 5%, measurement results begin to show errors; When the gas volume fraction exceeds 10%, the vibrating tube may even stop vibrating and cannot be accurately measured. 2.3 Analysis of the Impact of Improper Maintenance on Measurement Accuracy: After running for a period of time, flow meters may experience many problems, such as malfunctions, replacement or repair of certain components, and adhesion and blockage of oil impurities. If these situations are not handled properly, they can have an impact on the operation of the flow meter. For example, if the impurities in the oil are not treated
