KRACHT VCM Gear Flow Meter

Description

Overview

The KRACHT VCM gear flow meter is a high-precision volumetric measurement instrument built for the most demanding fluid technology applications, from hydraulic test benches to fuel consumption monitoring and dosing verification. Consisting of two intermeshing, high-precision gears driven directly by the fluid stream on the positive displacement principle, the VCM gear flow meter delivers outstanding repeatability across a measuring range spanning 0.008 to 700 l/min, media temperatures from −60°C to 210°C, and working pressures up to 480 bar. Its contactless, lid-mounted sensing eliminates the wear points that limit the service life of mechanical flow totalizers, making it a preferred choice for engineers who need dependable, long-term flow data without recalibration drift.

With engineering support in Muscat, Seven Star LLC supplies the VCM gear flow meter to hydraulic system integrators, marine operators, and process plants throughout Oman and the wider GCC. Facility engineers in Muscat, Sohar, and Salalah can source KRACHT metrology with full calibration documentation and regional technical support through Seven Star LLC – useful for test bench operators and OEMs who need traceable flow measurement with a formal quotation and the manufacturer datasheet.

Measurement Principle

The KRACHT VCM gear flow meter operates on the displacement principle: two precision-machined gears mesh together inside a sealed measuring chamber, and the liquid flowing through the meter forces the gears to rotate at a speed directly proportional to volumetric flow rate. The gears run in an almost contactless manner, supported by a combination of ball and plain bearings, with all moving parts lubricated by the measuring medium itself – removing the need for separate lubrication and reducing internal friction losses. Because the measuring principle requires no straight inlet or outlet piping runs to condition the flow profile, the VCM meter can be installed in compact skid layouts without dedicated settling sections.

Gear rotation is scanned in a fully contactless manner by lid-mounted sensors: as the measuring unit rotates through one tooth pitch, each sensor generates a signal corresponding to the geometric tooth volume. Dual-channel scanning delivers higher measurement resolution than single-sensor designs and simultaneously detects flow direction, allowing the VCM gear flow meter to report bidirectional flow without additional hardware. The practical result for plant engineers is low pressure drop across the meter body, high-response measurement suitable for dynamic test conditions, and accuracy that holds steady across a wide viscosity range – all without moving parts exposed to the process stream beyond the gear set itself.

Engineering Design of the KRACHT VCM

The VCM gear flow meter is housed in a compact, robust body engineered for demanding industrial and mobile environments, with electronics built to an EMC-compliant, RoHS-compliant design standard. The sensor lid assembly integrates directly with the gear chamber, keeping the signal path short and minimizing susceptibility to electrical noise in installations near variable-frequency drives or heavy switching equipment. Process connections and port sizing are selected to match the specified measuring range, and the meter accepts standard hydraulic fitting configurations for straightforward retrofit into existing piping and test bench manifolds.

Available output options include square-wave pulse signals for direct connection to counters and PLCs, encoder variants for maximized measurement resolution in laboratory and test bench applications, and IO-Link communication for simplified commissioning via IODD device description files. An analogue output variant is also available for control systems requiring standard current-loop signals, with cable-break detection and proportional LED indication of flow rate and direction built into the device. ATEX-rated versions extend the VCM gear flow meter’s application envelope into hazardous-area installations common across oil, gas, and marine fuel-handling systems.

Key Features

Buyers comparing the KRACHT VCM gear flow meter against turbine and ultrasonic alternatives will find the following features decisive. The KRACHT VCM gear flow meter is engineered to deliver dependable, high-precision flow data across a wide range of industrial and mobile hydraulic applications. Its key features include:

  • High-precision measurement with outstanding reproducibility across a wide measuring range of 0.008 to 700 l/min.
  • Contactless, dual-channel gear-position sensing that detects both flow rate and flow direction without added wear.
  • Low pressure drop and no requirement for upstream or downstream flow conditioners, simplifying installation.
  • Wide operating temperature range of −60°C to 210°C and working pressures up to 480 bar.
  • Self-lubricating gear set, with all moving parts lubricated by the measuring medium itself.
  • Multiple output options including pulse, encoder, IO-Link, and analogue signal variants.
  • EMC-compliant and RoHS-compliant electronics with optional ATEX-rated hazardous-area versions.
  • Compact, low-noise housing suited to both fixed installations and mobile hydraulic equipment.

Industrial Applications

The KRACHT VCM gear flow meter is deployed wherever accurate volumetric data matters, and the KRACHT VCM gear flow meter is specified wherever accurate volumetric flow data is essential for process control, fuel accounting, or test bench validation. Typical duties include fuel consumption measurement on marine vessels and generator sets, characteristic curve generation for hydraulic pumps and motors during factory acceptance testing, gear oil and lubricant filling line verification, indirect volumetric cylinder stroke measurement, and ratio control in two- and multi-component dosing systems used across chemical and industrial manufacturing. Its wide temperature and pressure envelope also makes it suitable for high-pressure hydraulic test rigs and micro-dosing applications where standard turbine meters lack sufficient turndown.

Backed by manufacturer datasheet documentation, Seven Star LLC distributes the VCM gear flow meter to hydraulic workshops, marine engineering firms, oil and gas service providers, and industrial test facilities across Oman and the GCC, including the industrial zones of Sohar and Salalah. Regional integrators building hydraulic power units, fuel monitoring skids, or dosing systems can source genuine KRACHT flow meters, calibration certificates, and replacement sensor components locally, reducing lead times for both new projects and urgent field replacements throughout the Sultanate of Oman.

About brand

KRACHT is the German maker of gear pumps, gear flow meters, hydraulic valves, motors and cylinders. The company was entered in the trade register in 1911 as Hillebrand & Kracht OHG and is based in Werdohl, in the Sauerland region of Germany. For most of its history it was a medium-sized family company; in January 2024 it became part of the Atlas Copco Group, in the Power and Flow division.

Seven Star LLC lists KRACHT pumps, flow meters, valves and hydraulic motors, and sources them by type key for machinery and marine users in Oman.
