1. What is the reason for the lack of pulse signal in the flowmeter? There are two main possibilities: one is that the fiber sensor has no output, and the other is that the conversion circuit board is faulty. The reason for the lack of signal from the sensor may vary depending on the principle of the flow meters ruler. For example, for a vortex turbine high wheel flow meter, the turbine may be stuck, and for a vortex street flow meter, if it is a pressure sensor, the pressure hole may be blocked. In short, specific issues need to be analyzed on a case by case basis. 2. What does flow meter pulse mean?
Flow meter pulse refers to a pulse signal generated by the flow meter when the measuring medium passes through.
. This signal can represent the flow rate of the measuring medium and is the core indicator parameter of the flowmeter. In many industrial settings, flow meter pulses are widely used in fields such as flow monitoring, control, and data acquisition. It has the advantages of high precision, good sensitivity, fast response speed, and strong stability, which can effectively improve the efficiency and accuracy of industrial processes. The principle of pulse generation in flow meters is mainly based on the laws of hormones or magnetic sensitivity for measurement. The hormone law measures the amount of electricity generated by the impedance change caused by the flow of a lead meter, while the magnetic sensitivity law generates pulse signals based on the influence of the medium on the magnetic field. Among these two principles, the application of magnetic sensitivity law is more extensive because it can achieve high-precision measurements over a wider range of flow rates and is not affected by the pr
3. How to convert pulse signal into flow rate
The method of converting pulse signal into flow rate usually involves determining the instrument coefficient of the flowmeter, and then converting the pulse signal into a flow rate value based on this coefficient.
. Specific operation process: Measuring pulse signal: It is necessary to measure the pulse frequency and number of pulses of the pulse signal. Pulse frequency represents the number of pulses emitted per unit time, while pulse count represents the total number of pulses emitted over a period of time. This is usually done using specialized electronic counters or frequency meters to ensure the accuracy of measuring the obstruction. Determine the instrument coefficient: The instrument coefficient is a key parameter that represents the fluid volume or mass corresponding to one pulse output by the flowmeter. This coefficient is usually calibrated by the flowmeter manufacturer at the time of leaving the factory and will be indicated in the product manual or nameplate. Calculate flow value: Calculate the flow value base
