Can a vortex flowmeter be used with a pulse output?

Project Overview

The vortex flowmeter can be equipped with pulse output function. Pulse output is one of the common output methods of vortex flowmeters. It can convert the measured flow rate into a pulse signal of a certain frequency or output the accumulated number of pulses within a certain period of time. This output method facilitates remote transmission and connection with various control systems, counters or Totalizers to achieve flow accumulation, display or control.

The pulse output modes of vortex flow meters include but are not limited to the following:

1. Signal frequency output: directly output the signal frequency detected by the probe, often used for calibration and calibration.

2. Correction frequency output: correct the real-time monitored signal according to the flow coefficient and then output it.

3. Frequency output: output the converted frequency signal. , the frequency has a linear relationship with the full-scale flow rate, for example, 1000Hz is designed to correspond to the maximum flow rate.

   

4. Pulse number output: Convert the accumulated flow rate into the number of pulses by setting the pulse equivalent. Factor to calculate, ensure that the number of output pulses in each calculation cycle is moderate (such as limiting each cycle to a maximum of 1000 pulses, less than 4 will be accumulated to the next cycle), and the pulse effective level is usually high level.

These output methods enable the vortex flowmeter to adapt to the needs of different industrial sites and achieve accurate measurement and control of fluid flow.
