The liquid flowmeter is manufactured according to the principle of Carmen vortex to measure the liquid in the sealed pipe.Now let's analyze the future and development of the liquid flowmeter.

Liquid flow meter of steam flow precision instrument, as a result of detecting element sealed in detecting the body, not measured medium, and their inside have no moving parts, no need for site maintenance, so favored by the majority of users praise highly, is widely used in textile printing and dyeing, petroleum, chemical, metallurgy, pharmacy, thermoelectric, papermaking, fire industrial metrology management and process control. With the scene shows 3.6 V battery power supply and power supply source and 4-20 ma output;Remote display can be equipped with secondary instrument LCD Chinese display, and can be compensated with temperature pressure.

The development of flow measurement can be traced back to ancient water conservancy projects and urban water supply systems.The orifice plate was used to measure the drinking water of the inhabitants in the caesars era of ancient Rome.The flow of the Nile was measured by weir in ancient Egypt around 1000 BC.China's famous dujiangyan hydraulic engineering application of the water level of treasure mouth water observation size and so on.In the 17th century, torricelli laid the theoretical foundation of differential pressure flow meter, which was a milestone of flow measurement.

Flow rate, pressure and temperature are listed as the three main test parameters.For a given fluid, the energy can be calculated as long as these three parameters are known. These three parameters must be tested in the measurement of energy conversion.

The liquid flowmeter sensor can be installed horizontally and vertically, and the fluid direction must be upward when vertical.Liquids should be filled with ducts and free of air bubbles.When installed, the direction of liquid flow should be consistent with the direction of the arrow on the sensor housing indicating flow direction.The upstream end of the sensor should have at least 20 times the nominal diameter of the straight pipe section, the downstream end should not be less than 5 times the nominal diameter of the straight pipe section, its inner wall should be smooth and clean, without indentation, scale and peeling, etc.

Integrated liquid turbine flowmeter is designed to be explosion-proof, which can show the total flow quantity, instantaneous flow rate and full flow rate percentage.The battery USES long-term lithium battery. The battery life of single-function meter can reach more than 5 years, and the battery life of multi-function display table can reach more than 12 months.

Turbine flowmeter is a type of liquid flowmeter whose rotating speed is detected by a sensor coil mounted on the outside of the housing.When turbine flowmeter blade cuts the magnetic force line produced by permanent magnetic steel inside the shell, it will cause the change of magnetic flux in the sensing coil.The sensing coil feeds the detected magnetic flux periodic change signal into the pre-amplifier, amplifies and shapes the signal, generates pulse signal proportional to the flow rate, and feeds the unit conversion and flow integrator circuit to obtain and display the accumulated flow value.At the same time, the pulse signal is sent to the frequency current conversion circuit, which converts the pulse signal into analog current flow, and then indicates the instantaneous flow value.
