Drip Meter Model NDR-6
- 8mm
This meter complies with JIS technical standards for specific measuring instruments.
Capable of measuring ultra low flow rate of 0.1L/h.
Low pressure loss eliminates the need for pumping.
No leakage due to the use of a magnetic coupling for counter transmission.
Since it is a standalone internal type, dust and air can be discharged through the drain outlet.
Pulse rate of the pump with transmitter (model GNDR-6) is 0.1L/P.
Please replace it after 5 years to maintain the performance.
Purpose of use
Measurement of kerosene consumption in housing complexes, etc.
●Note:
- (1) This meter operates with a natural drop-off. Please allow a drop of at least 30 cm between the kerosene tank and the combustor. If an oil server is attached, install the meter downstream of the server.
- (2) When pressurizing the piping to test for leaks, do so with the meter disconnected.
- (3) Install the filter.
- (4) Keep the inlet side valve open even when the meter is not in use.

- Make sure to place the kerosene tank so that its underside is at least 30 cm higher than the piping of the combustor.
Also, piping should be done in such a way that air does not accumulate. (Please also be sure to fully bleed the air inside the meter.)
→If the drop is insufficient or there is air accumulation, the meter counter may stop and kerosene may not be supplied. - When conducting a leakage test of piping, the applied pressure should be 0.1 MPa (1 kgf/cm2) or less. In addition, the test fluid should be pressurized and drained gradually so as not to exceed the maximum flow rate of 20 L/h.
→Sudden pressurization and discharge can damage the meter. - Install the meter so that it is level and the counter faces the front, paying attention to the entrance and exit.
→Accurate measuring may not be possible. - Do not close both inlet and outlet valves of the meter except for maintenance.
→If the temperature inside the meter rises in a sealed condition, the meter may break or leak due to increased pressure.
We recommend installing a strainer (100 mesh or more) or similar device to prevent foreign matter such as dust or rust from entering the meter. - Also, drain the meter on a regular basis.
→Contamination of foreign matter or moisture may cause meter performance degradation or immobility.
- Please read the instruction manual before handling the meter.
