Italian Oil meter HZ 3 for central oil supply – oil heaters – oil meter for perfect consumption control
The oil meter HZ 3 can be used as measuring device for fuel oil EL and diesel. Smallest amounts can be measured with highest accuracy. Just read out your oil consumption. The calibrated oil meter (10 years calibration validity) enables accurate consumer billing and is robust and long-lasting.
Installation also in oil central heating systems with single pipe system (suction capacity) possible, max -0.3 bar
| Technical data: Measuring accuracy + 1% Calibrated flow range 0.17 to 12 l/h Max flow range 30 l/h = 25 kg/h Heater output 1.65 kW to 275 kW Connection thread DIN 3852-X-G ¼” inner |
