Flowmeter is one of the key measuring instruments in industry. According to the physical characteristics of the measured material, it can be divided into liquid flowmeter and vapor flowmeter.Among them, there are many types of liquid flowmeters, common liquid flowmeters are: vortex flowmeter, pressurized flowmeter, electromagnetic induction flowmeter, ultrasonic flowmeter, volumetric flowmeter, differential pressure flowmeter, rotor flowmeter, open channel flowmeter, coriolis flowmeter, and so on.The principles and characteristics of various flowmeters are discussed below.

Laboratory micrometer

For the constant and accurate measurement of corrosive liquid, highly viscous liquid, toxic side effect liquid and other liquid level that cannot be accurately measured by general level instrument panel, acoustic frequency detection instrument should be adopted.

This series of flowmeters are widely used for precise measurement, adjustment and distribution of liquids, including industrial production, organic chemistry, crude oil and commercial automatic coffee machines.When used in the food hygiene and safety industry, the products are certified by the UK's national department for drug safety (NSF).

To tiny flow accurately measure instantaneous flowmeter is a kind of quality flowmeter, immediately is accurately measured flow panel using the heat conduction principle, namely the liquidity of the fluid mechanics and heat the original (fluid mechanics heating of the east and west blocks or accurate measurement outside the pipe heating body) between heat exchange association to accurately measure flow dashboard.The fast heat flowmeter for liquid is not suitable, because the fluid mechanics viscosity change, bubble, to the heat transfer and installation site are immediately harmful to its operation and characteristics.

Small liquid flow meters are professionally designed for the precise measurement of general liquids, high viscosity liquids such as syrups, petroleum, or extracted liquid detergents.Because of its unique structure and the swing line of the centrifugal impeller, will improve the accuracy of the measurement and verification of the liquid pressure drop is very small, wide detection range.Flowmeters can be used with different raw materials for the food industry or chemical industry.

Micro-flow meter is a special type of flowmeter which adopts the design scheme of supercharging principle to measure micro-flow accurately. It has high precision, especially under high temperature and high pressure.The electronic pulse counter is also integrated into the flow meter, which can maintain accuracy of ±1% and repeatability of ±0.25% under the standard of long-term continuous operation.Due to the smart overall design, settling is not easy to produce during work, so the dashboard is "clean" during work.Thus, even the most stringent requirements, such as the etchants used in the manufacturing processes of semiconductor materials integrated circuit chips and integrated IC, have strong corrosion resistance, and if a very small particle falls, the integrated IC will become waste, the wlr-w commodity can be considered.

At present, Shanghai porcelain flowmeter has been exported to more than 100 countries, involved in more than 100 industries.At the same time, the research and development of micro flowmeter also obtained the metrological certification.At home to fill the gap in the micro flowmeter, while breaking the monopoly of foreign enterprises.
