1. How to calculate the flow rate measured by a vortex flowmeter?

E=KBdV (where E - is the signal voltage (V) between the electrodes); B -- Magnetic flux density (large impulse T); D - Measure the inner diameter of the tube (M); V - Average flow velocity (M/S). ）In the equation, K and d are constants. Since the excitation current is constant, B is also constant. Therefore, from E=KBdV, it can be seen that the volume flow rate Q is proportional to the signal voltage E, that is, the signal voltage E induced by the flow velocity is linearly related to the volume flow rate Q. Extended Data Vortex Flow Meter is a volumetric flow meter produced based on the Karman vortex based simulation principle for measuring the volume flow rate, standard condition volume flow rate, or mass flow rate of gases, vapors, or liquids. Mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, steam, and other media. The characteristics of vortex flowmeter are small pressure loss, large range, high accuracy, and it is almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument can maintain a stable and long-lasting pulse count. The vortex flowmeter adopts a piezoelectric stress sensor with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃.

3. Calculation formula for frequency and flow rate of vortex flowmeter? In general, the flow equation of a turbine flowmeter can be divided into two types: practical flow equation and theoretical flow equation. Practical flow equation: qv=f/K formula 1; In the equation qm=qv ρ, qv and qm respectively represent volumetric flow rates, m3/s， Quality flow, kg/s; F is the frequency of the output signal of the flowmeter, Hz; K is the instrument coefficient of the flowmeter, P/m3。 According to the Instrumentation World Network, the coefficient of a turbine flowmeter can be divided into two segments, namely the linear segment and the nonlinear segment. The linear segment is about
