Drop-Flow Fuel Meter [Diaphragm Type]

Drop-Flow Fuel Meter 
- Diaphragm Type * Replacement every five years recommended for securing the specific performance.

Feature

  • Enable to measure 0.1 liter/h
  • No pump required because of quite low pressure loss
  • No leakage by using magnet coupling for transmitting rotation to numeral counter
  • Independent measuring mechanism allows removing debris and air in fuel through drain tap.

[Use Application]

For Measuring Kerosene Consumption on Centralized Kerosene Supply Piping for Multi-dwelling unit

[Precaution]

  1. Operated by gravity fall. Minimum 30cm head required between the tank (reservoir) and the burner.
  2. Remove the meter when the pressurized leak test.
  3. Provide a oil filter before the meter
  4. Open always the upstream valve to release the raised pressure inside due to temperature rise even while the season not requires the heating equipment.
