KRACHT Fluid Measurement Technology Series

Overview

The KRACHT Fluid Measurement Technology Series is KRACHT GmbH’s complete programme of gear-type flow meters, the instrumentation division that turns the same positive-displacement gear mechanism used in KRACHT’s pumps into a precision volumetric measurement tool. The series is built around the core VC platform and its output variants – VC Standard, VC with Encoder, VC with IO-Link, VC with Analogue output, the VC 0.01 micro-flow meter, and the aluminium-bodied VCA – each sharing the same gear-driven measuring principle but tuned for a different combination of flow range, signal interface and media compatibility. What unifies the family is contactless, wear-free sensing of gear rotation, which is what allows KRACHT flow meters to hold their calibration over long service life in demanding hydraulic, fuel and process-fluid applications, distinguishing this division from KRACHT’s pump and valve technology lines, which move and regulate fluid rather than measure it. Together these variants make up the KRACHT Fluid Measurement Technology Series.

Working closely with plant engineers in the region, Seven Star LLC supplies the full KRACHT Fluid Measurement Technology Series to industrial, marine, oil and gas, and process customers across Oman and the wider GCC. Whether a project needs a standard VC meter for general hydraulic flow verification, a VC with IO-Link for digital integration into a plant network, a VC 0.01 for micro-dosing accuracy, or an aluminium-bodied VCA for weight-sensitive skid applications, Seven Star LLC’s technical team helps select the correct variant, confirms flow and pressure compatibility, and backs every unit purchased from the KRACHT Fluid Measurement Technology Series with genuine KRACHT warranty and regional support.

Measurement Principle

Every meter in the KRACHT Fluid Measurement Technology Series operates on the gear-type positive displacement principle: two precision-machined, intermeshing gears are driven directly by the fluid stream passing through the meter body, and each rotation displaces a fixed, calibrated volume of liquid between the gear teeth and the housing wall. Because the gears are driven by the fluid itself rather than by an external motor, the rotational speed of the gear set is directly and linearly proportional to volumetric flow rate, and a contactless sensor mounted in the meter lid detects gear rotation without any physical contact with the wetted measuring elements.

This contactless sensing arrangement – whether read out as a simple pulse signal, an incremental encoder signal, an IO-Link digital interface, or a scaled analogue output – is what allows the same underlying gear-measuring mechanism to be packaged for very different plant integration needs across the series. Because there are no bearings or seals exposed directly to the sensing mechanism itself, KRACHT gear-type flow meters maintain accuracy over long service intervals, resist fouling better than turbine-type meters at low flow, and tolerate the full viscosity range and temperature extremes – down to −60°C in the standard VC and up to 210°C – that hydraulic and process fluids present in real installations.

Engineering Design of the KRACHT Fluid Measurement Technology Series

Across the KRACHT Fluid Measurement Technology Series, meter bodies are precision-machined from steel for the standard VC platform, rated to 480 bar and the widest temperature span in the family, while the VCA variant uses a lightweight aluminium housing rated to 240 bar for applications where weight and cost matter more than extreme pressure capability. The VC 0.01 micro-flow meter uses a scaled-down gear set and body specifically optimised for very low flows from 0.5 to 500 ml/min, where measurement resolution at low volumes is the primary design driver rather than pressure rating. All variants share the same lid-mounted contactless sensor housing, allowing the output electronics – pulse, encoder, IO-Link or analogue – to be swapped or specified per project without changing the underlying mechanical measuring element.

Interface and output electronics are where the series differentiates most clearly: the encoder variant adds a high-resolution incremental encoder capable of up to roughly 13.16 million impulses per litre for applications needing very fine flow resolution, the IO-Link variant provides a standardised digital fieldbus connection for direct integration into modern plant control architectures, and the analogue variant outputs a scaled signal with 16-bit resolution for straightforward integration into existing analogue instrumentation loops. Seven Star LLC’s existing KRACHT VCM gear flow meter, which shares the same contactless dual-channel sensing approach and a measuring range and pressure/temperature envelope matching the VC Standard platform, sits within this same family of KRACHT gear-type meters as a related model built on the same measuring principle that anchors the KRACHT Fluid Measurement Technology Series.

Key Features

The KRACHT Fluid Measurement Technology Series gives instrumentation engineers a genuinely broad flow-measurement toolkit from one manufacturer:

• Gear-type positive displacement measurement delivers high accuracy and repeatability independent of fluid viscosity within the design envelope.
• The VC Standard covers an exceptionally wide range from 0.008 to 700 l/min, at pressures up to 480 bar and temperatures from −60°C to 210°C.
• The VC with Encoder adds high-resolution incremental output, up to roughly 13,157,896 impulses per litre, for precision dosing and test-bench applications.
• The VC with IO-Link variant provides direct digital fieldbus integration for modern plant control and monitoring systems.
• The VC with Analogue output delivers a 16-bit-resolution scaled signal for straightforward integration into existing instrumentation loops.
• The VC 0.01 micro-flow meter measures from just 0.5 to 500 ml/min, purpose-built for low-volume dosing and laboratory-grade metering.
• The aluminium-bodied VCA reduces installation weight while still handling 0.02 to 200 l/min at up to 240 bar.
• Contactless sensing across every variant avoids wear on the measuring elements, supporting long-term calibration stability in continuous industrial duty across the KRACHT Fluid Measurement Technology Series.

Industrial Applications

The KRACHT Fluid Measurement Technology Series is deployed wherever accurate volumetric flow data drives process control or verification: hydraulic test benches and quality-control stations using the VC Standard or Encoder variants, fuel consumption monitoring on marine vessels and generator sets, chemical and adhesive dosing lines relying on the VC 0.01 for micro-flow accuracy, and weight-sensitive mobile or skid-mounted equipment specifying the aluminium VCA. In Oman and across the GCC, these applications map onto oil and gas processing and testing facilities, marine bunkering and fuel-monitoring operations, and the growing industrial base within the Sohar and Salalah economic zones, where hydraulic test benches and process dosing lines both depend on dependable flow verification.

With fast quotation turnaround and technical support, Seven Star LLC supplies the complete Fluid Measurement Technology Series to plant engineers, EPC contractors and marine operators throughout Muscat, Sohar, Salalah and the wider Sultanate, as well as neighbouring GCC markets, ensuring genuine KRACHT flow meter hardware, correct range and interface sizing guidance, and regional after-sales support are available locally rather than through a distant intermediary for every variant of the KRACHT Fluid Measurement Technology Series.
