The target flow meter output signal has 4-20mA, 0-10V, impulse, and RS485 outputs for options.

Turndown ratio is often referred to as the rangeability of an instrument. It is defined as the ratio of the maximum capacity of measurement to the minimum requirement for measurement. It is expressed as a multiplication factor from the lowest range to the highest range. Ultrasonic flow meter usually has a turndown ratio of  250:1.

The correct selection of the target flowmeter can ensure the better use of the target flowmeter. What kind of target flowmeter should be selected according to the physical and chemical properties of the fluid medium to be measured? The diameter, flow range, and output mode of the target flowmeter can be adapted to the nature

The accuracy of the vortex flowmeter is approximately ±0.5%R～±2%R for liquids and ±1%R～±2%R for gases, and the repeatability is generally 0.2%～0.5%. Because the meter coefficient of the vortex flowmeter is low, the frequency resolution is low, and the larger the diameter, the lower the accuracy, so the diameter should not be too large (below DN300).

The vortex flowmeter consists of two parts: a sensor and a converter. The sensor includes a vortex generator (bluff body), detection elements, meter body, etc.; the converter includes a preamplifier, filter shaping circuit, D/A conversion circuit, and output interface Circuits, terminals, brackets, and protective covers, etc. In recent years, intelligent flowmeters have also installed microprocessors,

The vortex flowmeter is a volume flowmeter that is researched and produced according to the Karman vortex principle to measure the volume flow of gas, steam, or liquid, the volume flow of the standard condition, or the mass flow. It is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid,

Pressure and temperature compensation Vortex flowmeter In the process industry, the pressure/temperature of steam/gas is usually not constant. If these effects cannot be compensated, huge measurement errors will result, resulting in energy and money losses. With built-in (optional) pressure and temperature measurement, pressure and temperature compensated Vortex flowmeters ensure the highest accuracy in determining vapor

As you may know, Vortex flowmeters use the principle called the von Kármán effect in their principle of operation. This principle dictates that flow is alternately responsible for generating vortices when traveling by a bluff body. According to the Vortex flow meter, a bluff body is described as a material with a broad and flat
