KOBOLD OME FLOWMETER

User Instructions

CAUTION: For safety reasons, please read the cautionary information located at

the end of the manual, before attempting installation.

1.0 General

The KOBOLD OME helical gear positive displacement flowmeter is designed to measure
the volume flow rate of clean, non-abrasive, lubricating liquids whose viscosities lie in the
range of 1 to 5000 cSt. The measuring principle of this fowmeter can be described as fol­lows:.

1. As the fluid to be measured is forced through the flowmeter by system
pressure, it causes the helical spindles (M) to rotate.

2. Each rotation of the spindle equates to an exact volume
of liquid which has passed through the flowmeter.

3. Permanent magnets are imbedded in the spindles; as
the spindle rotates, these magnets pass by a magnetic
pickup.

4. The pickup (I) generates a voltage pulse each time a magnet passes by.
These pulses can then be transmitted to a data acquisition device (A) where
the pulse frequency is translated into a rate of flow.

The helical gear design provides quiet operation, low pressure loss and few pulsations.
