KRACHT high-precision gear flowmeter from Germany, brand new in stock

KRACHT VC5The series gear flowmeter is based on the principle of volumetric measurement, and achieves flow measurement through the rotation of a pair of high-precision meshing gears in the measurement chamber. After the measured medium enters the flowmeter, the gear is driven to rotate, and a fixed volume of medium is discharged every time the gear rotates. The gear speed is transmitted to the counter or sensor through a magnetic coupling device, and the instantaneous flow rate and cumulative flow rate are obtained after signal processing. This principle ensures that measurement accuracy is not significantly affected by changes in fluid viscosity, density, and other parameters, and is suitable for measuring high viscosity media

Basic structural composition

Measurement chamber

High strength metal materials (such as stainless steel) are used for precision machining to ensure that the clearance between the gear and the cavity wall is controlled at the micrometer level, reducing leakage errors

gear pair

A pair of involute gears with the same module and equal number of teeth, surface hardened (hardness can reach)HRC60Above), excellent wear resistance

Bearing system

Adopting sliding bearings or rolling bearings design, choose according to the viscosity of the medium; High viscosity media are usually equipped with sliding bearings, while low viscosity media use rolling bearings to reduce frictional resistance

sealing assembly

Using fluororubber or polytetrafluoroethylene seals, with a wide temperature resistance range（-20℃~200℃）Ensure no medium leakage

Signal output unit

Including magneto electric sensors, pulse generators, or4-20mATransmitter, supporting digital and analog signal output

core functionality

Maintain within a wide viscosity range±0.1%The measurement accuracy meets the requirements of trade settlement level

Bidirectional measurement supports forward and reverse flow measurement, and can distinguish flow direction through signal processing

Signal output diversity provides pulses4-20mATheRS485（ModbusProtocol and other output methods for easy integration into automation systems

The intelligent models with self diagnostic function have fault alarm functions such as gear jamming and signal loss

performance advantage

High stability, simple mechanical structure, no vulnerable parts, average working time（MTBF）>50000hour

Wide viscosity adaptability can be stably measured from low viscosity hydraulic oil to high viscosity asphalt, without the need for frequent calibration

The rigid contact design between the high-pressure impact resistant gear and the cavity wall can withstand instantaneous pressure fluctuations (such as impact pressure in hydraulic systems)

Under normal operating conditions with low maintenance requirements, there is no need to replace components regularly, only every time2Annual inspection of aging of sealing components

major industries

Petrochemical industry: Measurement and transportation monitoring of crude oil, lubricating oil, resin and other media

Hydraulic and engineering machinery: hydraulic system flow detection, pump efficiency testing

Energy industry: fuel injection, heavy oil transportation and metering

Food and medicine: Quantitative filling of high viscosity syrup, ointment and other materials (using sanitary grade material models)

Automobile manufacturing: Flow monitoring of transmission oil and coolant circulation system

Typical application scenarios

Flow closed-loop control of hydraulic station system

Measurement of fuel consumption for ship engines

Accurate control of raw material injection volume in injection molding machines

Quantitative filling of lubricating oil production line

Monitoring of oil circulation in wind turbine gearbox

Installation method

Pipeline connection flange connection（DN10(Above) or threaded connection（DN6~DN8）Ensure the length of the straight pipe section for import and export (front)10Dafter5D，DFor pipeline diameter)

Installation direction: Horizontal installation (recommended) or vertical installation (gear shaft should be horizontal to avoid gear wear caused by gravity)

The flow direction requires strict installation according to the arrow on the shell, and reverse installation will increase measurement errors

Precautions

Upstream installation of media filtration is required80~100Eye filter to prevent solid particles from damaging gears

Before starting the exhaust treatment for the first time, it is necessary to exhaust the air in the pipeline to avoid the phenomenon of air pockets affecting the measurement accuracy

For high-precision measurement scenarios (such as trade settlement), it is recommended to configure temperature sensors for density compensation in temperature compensation

The maintenance cycle is to check the seals once a year3Annual precision calibration (using standard volume method or weighing method)

Outdoor installation of environmental protection requires the installation of a rain cover to avoid direct sunlight or low temperature freezing (below)-20℃Requires heat tracing)

KRACHT VC5The series gear flowmeter has become the preferred solution in the field of industrial flow measurement due to its high precision, wide viscosity adaptability range, and high reliability. Its modular design can be flexibly configured according to different working conditions (pressure, temperature, medium characteristics), and is widely used in industries such as hydraulic, petrochemical, and energy. During installation and use, attention should be paid to media filtration, pipeline exhaust, and regular maintenance to ensure long-term stable operation
