Energy Control with Brown
Check Your Energy Savings. Particularly Effectively After Building / Home Modernization
After modernizing a house, you should know whether your energy consumption has actually been minimized. The savings can be measured. The oil meters offer optimal oil consumption control, ideally before modernization, so that you can make an exact comparison afterwards.
When using an alternative energy source in addition to your heating system, you have an optimal comparison of the consumption values before / after. Your energy savings are made measurable with Braun oil meters.
Controlling your consumption is no problem with the easy handling of these oil meters. Save where it counts. Take advantage of the opportunity to determine at time of purchase what your oil requirement are and the price you should pay. Unlike other energy sources, where the price is dictated. BRAUN Oil Meter – an ideal addition to your heating system!

Oil Meter HZ 3
For central oil supply - oil stoves - measuring range 0.18… 12 l / h - burner output 1.65… 275 kW
Oil Meter HZ 3
The HZ 3 oil meter can be used as a measuring device for EL fuel oil and diesel fuel. Even the smallest quantities can be measured with the greatest accuracy, you simply read off your oil consumption. The calibrated oil meter (calibration is valid for ten years) permits accurate consumption calculations and is moreover extremely robust with a long service life. The HZ 3 oil meter can also be supplied if desired with calibration which is valid throughout the EU.

Oil Meter HZ 5 DR | Remote Counters
- Connection via screw terminals
- Reed contact: max. 30 VDC,
Imax = 6 mA, Rs = 1.0K ohms /
0.6W (note polarity) - Principle: The circuit of a counter or other recording device connected to the plus and minus terminals is closed via the reed contact and 1.0 K-ohm resistor. In order for the additional counter to reach its switching threshold safely, the input resistance should be at least 50 KΩ.
- Pulse value:
- 1 pulse = 0.02l
- 50 pulses = 1l
- Maximum frequency at 60l / h approx. 1Hz (use remote counter due to reed contact [-Prellen-] with damped input)
