• fuel oil meters forOEMs (originai equipment manufacturers),to be mounted under the burner cover • meters with lateral internai threaded connections • with 230 V Reed pulserto display measurement values on remote totaliser or on burner control unit • for mounting in horizontal, vertical orinclined positions CONTOIL® flow meters work on the volumetrie principle of rotary pi- ston meters (positive displacement meters).The main features ofthis me- asuring principle are large measuring ranges, high accuracy suitability for high viscosities and independence from power supply; flow disturbances do not influence proper operation. Rotary piston, guide roller and drive are the only moving parts in contact with the liquid.Their movement is transmitted by a magnetic coupling through a sealing plate.The hydraulic part is completely separated from the totalising module. Measuring error limits: Reference conditions Measuring error limits according to technical data of meter in % of actual value for the whole measuring range. Reference conditions Calibration oil similar to extra light heating oil, density at 20 °C = 814 kg/m3 Viscosity = 5.0 mm2/s according to DIN 51757 / ISO 3104 (corresponds to 4.1 mPa.s) Horizontal mounting, readings from counter CONTOIL® Oil meters are neverto be tested with water; otherwise they will get damaged.

For higher viscosities, or if the meter is installed on the suction side, the pressure drop and any reduction in the measuring range must also be taken into consideration Safety precaution When connecting the Reed pulserto a...
