Power VC 3As a high-precision volumetric flowmeter, the flowmeter has demonstrated significant advantages in special industries

Adaptability to harsh environments

Using high-strength metal materials (such as stainless steel)316L）It can withstand corrosive media, high temperature and pressure, and high dust conditions, and is suitable for industries such as chemical, petroleum, and metallurgy

Compatibility with low viscosity media

For low viscosity fluids such as hydraulic oil and lubricating oil (viscosity range)2-1000 cSt）It can still maintain stable measurement accuracy and meet the needs of fields such as mechanical manufacturing and ship engineering

Explosion proof safety design

Some models have passedATEXTheIECExCertification can be used in flammable and explosive environments (such as oil and gas fields, coal mines) to ensure operational safety

Functional scope

VC 3The flowmeter integrates multiple functions, covering the entire flow monitoring process

Real time traffic measurement through gears/The principle of elliptical gear meshing converts fluid volume into pulse signals, achieving accurate measurement of instantaneous and cumulative flow rates

Some models of medium condition monitoring have built-in temperature and pressure sensors, which can synchronously collect medium temperature（±1℃Accuracy and system pressure（±0.5%FS）

Data communication and control support industrial bus protocols (such asPROFINET）, accessibleDCS/PLCSystem, realizing remote monitoring and closed-loop flow control

Fault diagnosis has abnormal state alarm functions such as idle, overload, and signal loss, which improve system reliability

Temperature impact and response

The temperature range standard model is-20℃~120℃Stable internal performance, high-temperature models can withstand through insulation design200℃The low-temperature model uses special lubricants to ensure-40℃start

Temperature compensation built-inPT100Sensors monitor the temperature of the medium in real-time and compensate for the impact of viscosity fluctuations caused by temperature changes on accuracy through algorithms

Stress adaptation ability

Rated pressure, conventional model, design pressure350 barSuitable for high-pressure hydraulic systems; High voltage customized models can reach630 barMeet harsh scenarios such as deep-sea exploration and high-pressure cleaning

The sealing performance adopts metal bellows mechanical seal or magnetic drive technology, with no leakage risk, suitable for toxic and flammable media

Key factors in the usage process

Media compatibility

Applicable media include

Mineral oil, synthetic hydraulic oil, lubricating oil, diesel, kerosene, water-Ethylene glycol solution, etc

Not recommended for use with large particle impurities (>50μm）Or high volatility media (such as gasoline), need to be used in conjunction with a filter

Relationship between traffic and accuracy

Within the range10%-100%Within the range, maintain accuracy±0.1%; Below10%When measuring range, the accuracy decreases to±0.3%It is recommended to choose the appropriate caliber based on the actual flow rate (such asDN15correspond to0.5-50 L/min）

Influence of viscosity and head

An increase in viscosity will increase rotor resistance, and it is necessary to ensure that the system drive pressure is sufficient (recommended minimum inlet pressure)0.5 bar）

Viscosity lower than2 cStWhen there is a possibility of leakage, a low viscosity specialized model should be selected

head

The flowmeter itself does not generate head, and the pressure loss is relatively small（≤0.5 bar@Rated flow rate), negligible impact on system head, suitable for series connection in hydraulic circuits

Advantage Performance Analysis

The principle of high-precision and high repeatability volumetric measurement is not affected by flow conditions, and its accuracy is much higher than that of turbines or electromagnetic flow meters, especially suitable for scenarios such as trade settlement and process control

Compact structure and low maintenance with no vulnerable parts (such as impellers), average working time（MTBF）＞50000Hours, with a long maintenance cycle2year

Range ratio can reach1:20Meet the full operating condition requirements from small flow leakage monitoring to full load operation

Strong anti-interference ability, insensitive to pipeline vibration and electromagnetic interference, can be directly installed at the pump outlet or near the valve position

Application Fields and Scenarios

Installation method

Installation position: Horizontal installation (priority) or vertical installation (fluid from bottom to top), to avoid the accumulation of bubbles; Reserved before entrance5Double diameter straight pipe section, no requirements for outlet

The flange connection method must comply withISO 5211Standard, threaded connection adoptsNPTorGThread, ensure sealing (metal gasket is recommended)

Electrical installation signal lines need to be shielded and kept away from strong electrical cables; Explosion proof models need to be according toATEXStandardize grounding, grounding resistance<4Ω

Precautions

Media preprocessing must be installed100μmFilter (filter precision)≤The maximum particle size in the medium1/3）To prevent rotor jamming

Slowly open the valve during start-up and shutdown to avoid instantaneous impact; When not in use for a long time, the medium should be emptied to prevent freezing or corrosion

It is recommended to calibrate once a year using standard volume tubes or weighing methods to ensure that the accuracy meets the requirements

Environmental protection: Rainproof cover is required for outdoor installation, and nickel plated or Hastelloy alloy shell material should be selected for corrosive environments

Power VC 3Flow meters have become the preferred solution for flow measurement in special industries due to their high precision, high reliability, and wide adaptability

Industrial grade design suitable for harsh working conditions, meeting the requirements of high temperature, high pressure, and corrosive media

±0.1%High precision and low maintenance costs, reducing the total long-term usage cost

Multi signal output and communication protocol, seamlessly integrated automation system

Extensive industry application case verification, especially outstanding performance in the fields of hydraulic, petrochemical, and energy
