VSE Flow Meter

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 tooth produces one impulse.

The space between the gear teeth, when fully enclosed on both sides by the housing, constitute measuring chambers. Fluid flow causes the gears to rotate and the incoming flow is separated into discrete volumes within these chambers i. e. the volume of liquid passing through the unit will cause rotation of the gears by exactly one tooth pitch.

This volume is known as the Volume/Impulse (Vm) and is stated in cc/Imp. It is used to define the size of a flow meter.

PICK-UP SYSTEM

The non-contact pick-up sensors consist of two differential magneto resistors which are circumferentially offset from one another by 1/4 of a tooth pitch. The signals of both pick-up sensors are digitized with two signal amplifiers and amplified via followed shortcircuit proof push-pull output stages.

The square wave output signals are bidirectional and may be simply processsed by any external electronics, plc control or computer. The processing of the 90 phase angle between signals enables recognition of flow direction and impulse rate conversion with a factor of 1, 2 and 4.

The signal frequency is proportional to the momentary flow rate (volume rate) dependent on the particular flow meter size. The frequency range extends from 0 - 2000 Hz. The preamplifier is protected against reverse polarity and incorrect connection. For medium temperatures between -30 C and 120 C (-22 F and 248 F) the unit is mounted directly on the flow meter cover.

For liquid temperatures up to 210oC (410oF) a special pick up system is available.
