1. What does the output pulse signal of an electromagnetic flowmeter mean?

Electromagnetic flowmeters generally output a current signal of 4-20mA, and the pulse signal of the "La Sui Bu Que Shan Chong" is the frequency signal.

2. Flow meter pulse output Cumulative flow rate

The core relationship between flow meter pulse output and cumulative flow rate is that the cumulative flow rate is calculated by accumulating the number of pulses and multiplying it by the pulse equivalent.

. 1. Core concept: Numerical pulse output: The flowmeter converts instantaneous flow into electrical pulse signals, and the signal frequency is proportional to the flow rate. The larger the flow rate, the higher the pulse frequency. Cumulative flow rate: The total amount of fluid flowing through a flowmeter over a period of time, which is the integral of instantaneous flow rate over time.

2. Calculation principle: The formula for calculating cumulative flow rate is: cumulative flow rate=total number of pulses x pulse equivalent (K-series potato stem number). Pulse equivalent (or K coefficient) is a core parameter that refers to the fluid volume represented by each pulse (e.g. 1 pulse=0.01 liters). This parameter is determined by the flowmeter model and is usually clearly calibrated in the calibration certificate or product manual.

3. Implementation Method: PLC (Programmable Logic Controller) or flow integrator are commonly used in industry to receive pulse signals. These devices have high-speed counters inside, which accumulate and count pulses, multiply them by a preset K coefficient, and finally display or output the cumulative flow value. This technology is widely used in scenarios that require accurate m

easurement and batch control, such as raw material proportioning in the chemical industry, trade settlement in water treatment and energy fields (water and gas metering), and its high-precision characteristics are the basis for achieving accurate control and fair billing.

3. What is the pulse frequency of the input signal of the flowmeter?

This means the frequency of the pulse signal received by the flowmeter.

. Pulse signal is an output method of flowmeter, which is directly proportional to the flow rate. Therefore, the frequency of the pulse can reflect the changes in flow rate. In practical applications, the pulse frequency signal of the flowmeter can have multiple input methods. The pulse frequency signal of the flowmeter can be input into an isolated transmitter that converts the pulse frequency signal to voltage or current signal at 2500VDC. The pulse signal of the flowmeter can also be measured by high-speed input pulses.

4. What does cumulative flow pulse signal mean?

It means: the pulse signal generated by the cumulative flow of liquid or gas measured in the flowmeter.

. When a liquid or gas flows through a flowmeter, the flowmeter will emit a certain number of pulse signals, each representing a certain volume or mass of flow. By calculating the number of pulse signals, the cumulative flow rate of the liquid or gas can be obtained. This pulse signal is output in the form of a digital signal, which can be read and processed by a counting machine or other intelligent devices.
