• Volume display on roller counter, in litres • fuel oil meterwith threaded orflanged ends • for horizontal, vertical or inclined mounting Option: Reed pulser or RV / IN pulser Versions available on request: • different flange drillings, such as ANSI,JIS 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 mmVs 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.

Technical data 2) I US gallon corresponds to 3.785 litres 3) For burners and engines or motors, the meter must be selected on the basis of the permanent flow rate. 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 4) Min.flow rateVZO 15 with IN-pulser: 15 l/h 5) Weight without couplings. Thistype of pulser is irrtegrated into the rollercounterandthus is especially appropriate for remote totalisation. For otherapplications the IN inductive pulser is preferable. Switching...
