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