Flow Transmitter / Screw Volumeter LABO-VHS-I / U / F / C
Flow Transmitter / Screw Volumeter LABO-VHS-I / U / F / C
● Measures and monitors viscous media (oil) 1.4..2500 l/min
● Connection G 1..G 21/2
● Very low dependence on viscosity
● Can be used up to 40,000 mm²/s (cSt)
● 0..10 V, 4..20 mA , frequency/pulse output, completely
configurable
● Light and compact device (aluminium housing)
● Operation and measurement possible with forward and
reverse flow
● For cost-sensitive applications
Characteristics :
The VHS flow transmitter measures the flow using the volumetric
principle, and is suitable for fluid, viscous, lubricant media (e.g.
lubricating oil). If the material for the VHS is selected appropriately,
aqueous fluids such as soaps, pastes, and emulsions with
non-abrasive characteristics can also be measured, as long as they
have sufficient lubricity.

The VHS flow transmitter measures the flow using the volumetric
principle, and is suitable for fluid, viscous, lubricant media (e.g.
lubricating oil). If the material for the VHS is selected appropriately,
aqueous fluids such as soaps, pastes, and emulsions with
non-abrasive characteristics can also be measured, as long as they
have sufficient lubricity. Because of the volumetric functioning
principle, the device is almost completely independent of viscosity.
The VHS system consists of two interlacing screws which run in
opposite directions, driven by the flowing medium. A magnetically
pre-tensioned Hall sensor positioned outside the flow space detects
the screw flanks, and creates a frequency signal proportional to the
flow. Here, every pulse corresponds to a specific measured
volume. There are no magnets in the flow space.
The LABO-XXX-I/U/F/C electronics make various output signals
available:
● Analog signal 0/4...200 mA (LABO-VHS-I)
● Analog signal 0/2..10 V (LABO-VHS-U)
● Frequency signal (LABO-VHS-F) or
● Value signal Pulse / x Litres (LABO-VHS-C)
A model with switching output is also available (see separate
datasheet). If desired, the range end value can be set to the
currently existing flow using "teaching".
