1. What kind of flowmeter requires a flow integrator, what kind of flowmeter needs a differential pressure transmitter, and what kind ..
Simply put:
1. What kind of flowmeter requires a flow integrator? Answer: Non intelligent flow meters. The most basic feature is that it does not have on-site display function, nor does it have functions such as integration, temperature and pressure compensation, alarm output, etc. This type of flowmeter (more precisely, it should be called a flow sensor) needs to be equipped with a flow sensor and an accumulator.
2、 What kind of flow height gauge needs to be equipped with a differential pressure transmitter? Answer: Differential pressure flow sensors (or throttling devices) need to be equipped with differential pressure transmitters because their measurement principle is based on the difference in pressure (i.e. differential pressure), hence the name.
3、 What kind of flowmeter requires temperature and pressure compensation? Answer: Generally speaking, gas and water vapor have a direct relationship with the temperature and pressure inside the fluid pipeline due to their volume, flow rate, and mass flow rate. Therefore, temperature and pressure compensation is generally required for accurate measurement.
4、 What is pulse? Answer: Pulse in the field of flow measurement instruments generally refers to the frequency pulse or volume pulse signal output by the flowmeter, which has a certain operational relationship with the fluid flow measured by the flowmeter.
2. What is the reason for the difference in displayed values between the vortex flowmeter and the accumulator?
There may be several reasons why the displayed values of the vortex fl
1. Calibration differences: The vortex flowmeter and the integrator may have undergone different calibration processes, and there may be differences in calibration methods and standards.
. This may lead to differences in measurement range or accuracy between the two, resulting in inconsistent displayed values. Flow rate range: Vortex flowmeters and integrators may have different linear ranges when measuring steam flow rate. If the flow rate exceeds the linear range of a certain device, it may cause inconsistent display values. Fluid parameters: The measurement results of vortex flowmeters and integrators may be affected by fluid parameters such as steam temperature, pressure, or density. If the response codes of these parameters are different between the two, it may result in inconsistent displayed values. 4. Data processing algorithm: Vortex flowmeter and accumulator may use different data processing algorithms to calculate flow rate. The accuracy and calculation methods of these algorithms may vary, resulting in inconsistent displayed values. The methods to solve this problem include: 1. Calibration and adjustment: Calibrate the vortex flowmeter and accumulator to ensure they are calibrated according to the same standards and make necessary adjustments to reduce differences. 2. Determine the working range: Understand the working range of the vortex flowmeter and accumulator, and ensure that their data is consistent when used. 3. Determine fluid parameters: Confirm the temperature, pressure, density, and other parameters of the steam, and ensure that the vortex flowmeter and accumulator can handle these parameters correctly. 4. Comparative testing: Use other reliable fl
