Precise and reliable systems of oil dosing are necessary at oil filling operations. Dosing mechanisms are equipped with flowmeters in two versions— with the function of dose setting and control over pumps and valves or simply in the form of a flowmeter metering device to measure the pumped fluid amount. By order — Explosion-proof version in compliance with the Atex requirements.

The pump is selected depending on the oil type and operating conditions. Performance from 5 lpm to 1,000 lpm. As a rule, our customers order dosers with the performance 10, 25, 50, 100, 200 and 300 lpm. A reliable keyboard allows easy and convenient control of fluid dispensing or dosing. Keyboard blocking. Fine filter with the filtering degree to 1um guarantees that filled oil will be clean.

Doser structure

  • A doser consists of three functional blocks: Pumping; measurement; control.
  • The pumping block comprises transfer or dosing pumps.
  • The measurement block is intended for measuring the liquid flow, forming and transferring the signal on the current value of the flow rate to the control block.
  • The control block consists of a controller, a display with a button bar, electronic automatic devices kit (relay, protection automatic devices, starter units, etc.) and a cut-off valve. The control block can comprise one or two cutoff valves depending on the filling pattern.

Doser operating principle

The doser can operate both in the manual or automatic mode. In the automatic mode the dose is dispensed after the signal received from the devices which are not included in the doser structure. In the manual mode the dose is released after the signal from the button bar. After the signal transfer, the control block starts the pump, opens the valve and receives the flow rate information from the flowmeter. When a set dose is dispensed the controller closes the valve and stops the pump.
