- Reliable monitoring and flexible control of the system
- Accurate measurements
- A reliable solution with everything from a single supplier
- Simplifies consumption optimizing
Operating principle :
Function :
CONTOIL flow meters work on the volumetric principle rotary piston meters (positive displacement meters).
The main features of this measuring principle are large measuring range, high acuracy, suitability for high viscosities and independence from power supply;flow disturbances do not influence proper operation.
Leading manufacturrs of oil burners and operators of hearing systems, ships or diesel engines relyon CONTOIL fuel oil meters – and good reasons.
Technical Data :
• with electronic display of total volume,resettable volume and flow rate,units: litres or US gallons 2)
• fuel oil meter with threaded or flanged connection
• for mounting in a horizontal,vertical or inclined position
Option:with inductive INA pulser
Versions available on request:
• different flange drillings,such as ANSI,JIS
