Flow meter

The mass flow meter can be used in the following fields to meet the requirements of ingredients, mixing processes, and commercial measurement. Chemical: containing a chemical reaction system. Petroleum: moisture content analysis. Lipids: including vegetable oils, animal fats, and other oils. Liquid Flow Sensors That Provide Accurate Flow Rate Measurement. Pharmaceutical. Painting. Precision Measurement & […]

Coriolis mass flow meters are of high measurement accuracy. A liquid mass flow accuracy of 0.1% is common and 0.05% is also available. Gas mass flow accuracy to 0.25% is available, although 0.35-0.5% is a more common selection.

Target flowmeters measure flow by measuring the amount of force exerted by the flowing fluid on a target suspended in the flow stream. The force exerted on the target by the flow is proportional to the pressure drop across the target. When flow medium flows through measure tube, the pressure will force on the target

Trouble Shooting The flow meter displays non-zero, while the flow velocity is zero. The following reasons and solution methods may be included Flowmeter was not installed in a strictly horizontal position. Solution: zero set operation. Flowmeter has run for a long time and error occurs. Solution: zero set operation. Overloading brings zero offsets. Solution: zero

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,
