A gear flow meter is a flow measurement instrument that calculates flow by measuring the rotation of gears produced when liquid or gas passes through a pipe. This kind of flow meter is widely used in industrial production, energy, petrochemical and other fields, and is one of the most common instruments in the field of flow measurement. This article will introduce the user manual of the gear flow meter, including its applicable working conditions, non-applicable conditions, and the recommended gear flow meter brand Doweston.

1. Applicable working conditions of gear flow meter

The gear flow meter is suitable for measuring fluids with a viscosity not greater than 2000 mPa - s, a liquid temperature not higher than 120°C, and a gas temperature not higher than 80°C. At the same time, this kind of flow meter has certain advantages for measuring low viscosity, medium and high temperature, and corrosive liquids. Gear flow meters have high measurement accuracy in liquid measurement, usually reaching 1%~0.5%. In terms of gas measurement, due to changes in gas density, its accuracy is relatively low, generally 1.5%~2.5%.

2.gear flow meterInapplicable conditions

Although gear flow meters perform well under many operating conditions, there are some special conditions where they are not suitable. First, gear flow meter are not suitable for measuring high viscosity fluids. When the liquid viscosity is greater than 2000mPa - s, the measurement accuracy of the gear flow meter will drop significantly. Secondly, gear flow meters are not suitable for measuring fluids under high pressure differences. When the pressure difference is greater than 10MPa, the fluid will cause damage to the gear of the gear flow meter, thus affecting the measurement results. In addition, gear flow meters are not suitable for measuring fluids with high temperature and high pressure, because under such conditions, the gears of the gear flow meter are easily deformed or damaged.

3. Recommended brands:Doweston gear flow meter

DowestonIs a company specializing in the production of instruments and meters, and its products are popular in domestic and foreign markets. Doweston gear flow meter has the characteristics of compact structure, small size and easy installation. The gear material is made of high-strength, high-durability stainless steel or wear-resistant materials, which can meet the needs of various working conditions. At the same time, its sensor uses a magnetic sensor, which can achieve high-precision flow measurement.

Doweston gear flow meter also uses advanced digital signal processing technology and automatic temperature compensation technology to accurately measure the flow of various media. In addition, it has self-diagnosis and automatic fault detection functions, which can automatically alarm faults to ensure the reliability and stability of the flow meter. The advantage lies not only in accuracy, reliability and stability, but also in its wide applicability. Regardless of the type of fluid medium, flow range, temperature range, viscosity, pressure, corrosiveness, etc., Doweston gear flow meter can meet the needs of use under different working conditions.
