• 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.
