German VSE gear flow meter spot parameters Shanghai Weite Rui

AllGear flow meterVS2The series is based on the principle of volumetric measurement, with the core component being a pair of high-precision meshing gears. When the measured medium flows through the flowmeter, the gear is driven to rotate under the pressure difference of the medium. Every time the gear rotates, a fixed volume of medium is discharged. By using sensors (such as magneto electric or photoelectric) to detect the number of rotations of gears, mechanical rotation is converted into electrical signals, and the instantaneous flow rate and cumulative flow rate are calculated by the signal processing unit. Its measurement accuracy is not significantly affected by changes in fluid viscosity, making it particularly suitable for precise measurement of high viscosity media

internal structure

The high-precision machining of the measuring chamber provides stable rotational space for gears, ensuring the accuracy of measuring volume

Gear pairs are usually two involute gears with the same module and equal number of teeth, made of wear-resistant materials (such as hardened steel or special alloys) to ensure long-term stable operation and minimal clearance leakage

The bearing system adopts high-precision rolling bearings or sliding bearings to reduce gear rotation resistance, improve measurement sensitivity and service life

The sealing components include shaft seals and chamber seals to prevent medium leakage and are suitable for different pressure and temperature conditions

The signal generator is installed at the end of the gear shaft and generates a pulse signal proportional to the gear speed through magnetic coupling or photoelectric induction, achieving non-contact measurement

Suitable for various liquid media, including corrosive liquids (corresponding corrosion-resistant materials should be selected)

High temperature and high pressure adaptation. Special models can work stably under harsh temperature and pressure conditions

Low viscosity adaptability: By optimizing gear design, it is possible to measure as low as0.3 cStLow viscosity medium

The temperature range standard model operates at a temperature of-20°Cto+120°CWhen using high-temperature materials such as Hastelloy, it can be extended to-40°Cto+200°CTemperature changes may affect the viscosity of the medium, and the potential impact on measurement accuracy needs to be considered when selecting

The working pressure of conventional models is160 bar（DN 4-DN 25）Large caliber models（DN 40-DN 50）Usually it is63 barSpecial high-voltage models can reach400 barDuring installation, it is necessary to ensure that the system pressure does not exceed the rated pressure of the flow meter to avoid overload damage

The characteristics of the medium need to be clearly defined, including viscosity, corrosiveness, and the presence of particulate impurities. When containing particles, a filter should be installed to avoid gear wear

Flow stability: Avoid severe flow fluctuations and install buffering devices if necessary to ensure measurement accuracy

Installation direction: Usually installed horizontally, some models can be installed vertically (need to confirm the direction of the gear shaft to avoid gravity affecting the bearing life)

Upstream and downstream straight pipe sections: Although volumetric flow meters have lower requirements for straight pipe sections, it is recommended to retain them upstream5Double pipe diameter, downstream retention2Double diameter straight pipe section reduces flow field interference

Application field scenarios

Industrial process control: chemical reaction kettle feed metering, lubricating oil circulation system flow monitoring

Energy metering: fuel injection, hydraulic system energy loss analysis

Food processing: quantitative transportation of high viscosity materials such as chocolate and syrup

Automotive testing: dynamic monitoring of engine lubricating oil flow, transmission oil circulation testing

Pharmaceutical industry: precise proportioning and filling of drug solutions, in compliance withGMPstandard

Installation method

Choose flange, thread or clamp connection for pipeline connection according to the model to ensure good sealing and avoid leakage

The flow direction identification is strictly installed according to the flow direction arrow on the flowmeter housing. Reverse installation may cause measurement errors or damage to internal components

The installation position should avoid being installed at the outlet end of the pump (which is prone to air pockets). It is recommended to install it at the suction end of the pump or at a high point in the system to ensure that it is filled with the medium

Electrical connection signal lines need to be shielded to avoid electromagnetic interference and have reliable grounding

Precautions

Media filtration is installed upstream of the flowmeter100-200Eye filter to prevent solid particles from damaging gears

Ensure that the flow meter is filled with medium when starting the system to avoid idling, as idling may cause dry friction and wear on the gears

Regular calibration is recommended to be conducted once a year to ensure that the measurement accuracy meets the requirements

Maintenance: Regularly replace seals and bearings based on the characteristics of the medium to maintain the equipment in good condition

Low temperature start-up is necessary for high viscosity media. Preheating is necessary at low temperatures to avoid gear jamming caused by sudden increase in viscosity
