POSITIVE DISPLACEMENT FLOWMETER

VS positive displacement flow meters are volume rate measuring sensors based on the meshing gear principle and are designed for use with liquids. Two precisely matched gear wheels are enclosed in a very accurately machined housing. Gear rotation is sensed by a noncontacting signal pick-up System. Each work produces one signal.

VS SERIES

HELICAL SCREW FLOWMETER

RS flow meters measure the flow rate based on the screw pump principle. The newly developed rotor profiles ensure a low-resistance, high-precision measurement while gently transporting the measuring medium.

RS – SERIES

ALUMINUM POSITIVE DISPLACEMENT FLOWMETER

The VSE EF ecoflow is an inexpensive alternative to the VS Series for measuring tasks with lower standards of technical characteristics such as accuracy, pressure, temperature, etc.

EF – SERIES

GEAR FLOWMETER

VHM – SERIES

TURBINE FLOWMETER

Turbine flow meters are precise and reliable measuring equipment, designed for varied applications. VTR flow meters can be installed even under the harshest application conditions including oil, petrochemical and chemical industries as well as other industrial sectors.

The positive displacement gear flow sensors of the VHM Series are based on the meshing gear principle and were developed for high precision flow metering for a wide variety of liquids, especially liquids with high abrasiveness and poor lubricity. Each tooth generates an impulse by recognition of the gear rotation by a non-contact detection system according to the carrier frequency principle. Additionally, the flow sensors of the VHM Series are dead spaced optimized for (easy flushing) use in the paint industry and for paint spraying systems.

Helical Screw Flow Meter RS type

Diposkan pada Februari 16, 2015 oleh Yugo Nugroho Boyolali

VSE optimized material and technology in the bearing area. The combined radial / axial slide bearing is shielded behind bearing brackets shaped to be flow-optimized. The bearings are made from tungsten carbide and, first time in positive displacement flow meter, also made from silicium carbide (SSiC).

A sensor module was developed that enhances the functionality of the RS flow meter significantly. The sensor itself features two GMR bridges (sin / cos) and is housed in a removable stainless steel cartridge case together with a signal conditioning and amplifier unit. The downstream electronics unit features a high-resolution sin / cos-interpolator. Among others, the device features a programmable signal filter, which is able to offset unwanted, negative pulse sequences and detects and saves values that exceed the indicated flow and temperature values. A separate directional signal is available for 1-channel evaluations.

Performance data

Flow range 0 up to 3.000 l/min

Pressure range up to 450 bar

Temperature range -30 up to +120°C

Frequency range up to 100 kHz

Viscosity range 1 up to 1.000.000 cSt

Applications

Process technology

Hydraulics

Highly viscous, paste-like, abrasive adhesives and sealants

Advantages

High precision mostly independent of viscosity

Gentle fluid measurement

Pulsation-free measurement

Lowest pressure losses

High on functionality due to intelligent sensor technology

Short response time through reduced mass

VSI Series – High definition with special preamplifier

As a very high resolution is necessary for precise and exact flow measurements, the volume measurement Vm must be resolved even more than with conventional preamplifiers. VSE has therefore developed the preamplifier with interpolation, with which a selectable resolution of up to 64 flanks (16 pulses) per period can be attained.

This individually programmed high resolution enables to set the volume measurement Vm optimally for each provided case of application. Furthermore, new applications can be availed with the higher resolution. With the VSI flow meter, measuring, controlling and regulating in lower flow ranges, in zero flow, in both flow directions as well as dosing and filling of small volumes becomes possible.

Advantages

Accurate volume measurement

Fast detection of flow changes

Higher accuracy, faster response times

Higher frequency with low flow rates

Measuring media with high viscosity

Precise measurement and dosage of volume

Better and more precise operations of digital controls

Faster and better analogue output
