Low Flow Liquid Turbine Flow meter
SLW-Micro Series Low flow liquid flow meter is based on turbine flow meter principle which is dedicated to measure liquid flow rate with low flow rate. The microliter flow meter has high accuracy even at high temperature and high pressure conduction. The electronic pulse generator is built-in the flow sensor, and can keep±1% accuracy and ±0.25% high degree of repeatability under continuous running.

Working principle of Low Flow Liquid Turbine Flow meter
The rotational angular velocity of the impeller placed in the fluid is proportional to the fluid velocity, and the velocity of the fluid to be measured is obtained by measuring the rotational angular velocity of the impeller, thereby low flow turbine sensor is obtaining the flow value in the pipeline. Low flow turbine flow meter makes full use of the fluidity of the liquid to drive its internal machinery to rotate, and then uses its internal careful design to make it rotate with the help of physics knowledge to drive the instrument to run.
Ultra low flow Turbine flowmeter relies on the impact of the fluid flowing through the pipeline on the impeller blades in the pipeline to drive the impeller to rotate, and the flow rate of the fluid is proportional to the angular velocity of the impeller. Turbine flowmeter structure includes a casing, front and rear guide frames, impellers, bearings and magnets. Miniature turbine flow meter shell is connected to the external pipeline, the internal structural components are fixed, and the fluid entering the shell is micro-rectified; the hollow hub of the impeller is equipped with magnetic steel, and the two ends are equipped with bearings, which cooperate with the guide frame to ensure the stable rotation of the impeller and realize the flow rate metering.
Liquid energy can be used in the micro flowmeter to drive its operation, but it is necessary to choose the appropriate liquid, and it is not suitable to use too viscous liquid. If the fluidity is poor, so when the flow is metered, there is also a lack of power, which causes problems with its stable operation. The low flow turbine flowmeter is also affected by surrounding factors, which can cause deviations in its results, so it is necessary to avoid the influence of these factors (such as surrounding pressure, temperature, etc., which will affect it). When using liquid media, pay attention to whether it is pure, and try to avoid other impurities that affect the micro liquid flowmeter.
Liquid can be measured by low flow turbine flow meter
The fluid measured by low flow turbine flow meter is required to be relatively clean and no corrosive liquid. Recommended fluids such as petrochemicals: naphtha, ethylene, styrene, polyethylene, liquefied petroleum gas, natural gas, liquid oxygen, liquid nitrogen, carbon dioxide, chemical solutions, ammonia, brine, methanol, Water, high-pressure hydrogen, organic liquids, alcohol, ether, benzene, toluene, butadiene, carbon tetrachloride, etc.
Matters need attention when using Miniature turbine flow meter
It is necessary to choose a suitable fluid. If the viscosity of the fluid is too high, it is not conducive to its normal operation, so it is necessary to choose a fluid with a small viscosity coefficient by low flow turbine flow meter. However Silver automation instruments ltd also has solution for high viscosity low flow liquid measurement.
The rotating speed of the flowmeter should not be too high during operation. If the rotating speed reaches the critical value, it is easy to cause damage to the flowmeter, which will cause the inertia of its internal components and cause damage to the equipment. Therefore, it should be set within a reasonable range to improve usage time.
