Braun HZ Oil Meter

The Braun range of HZ Oil Meters must not be installed directly outdoors, otherwise issues can be caused by the weathering conditions of rain and other precipitation. Prolonged sunlight exposure can also be harmful to the Meter lifespan and functionality. If a HZ Oil Meter must be installed outdoors then a protective enclosure should be installed to keep it safe and functioning correctly. Generally the rating of the enclosure should be IP68 or higher.

The HZ3 from Braun is an Oil Meter designed for small sized systems. Mediums of Extra Light Fuel or Diesel Fuel can be measured through the HZ3 as standard. This Meter can be installed on both Oil Based Central Heating and also Suction systems with a single pipe for boilers or burners ranging from 1.65 kW up to 265 kW. The connection on the meter is a 1/4" internal thread with the inlet and outlet on the bottom of the Meter itself.

The dial on the HZ3 has a revolution counter which will make a full rotation when 1 Litre of Oil is measured through the Meter and in turn will increase the reading on the index dials that show the totalised volume. This large display is easy to read and is part of the robust design in order to provide a reliable Meter. 

Also available is the larger model, the HZ5. This allows the measurement of Oil supplies on slightly larger installations with burners and boilers working between 7 kW to 400 kW. The HZ5 Meters are supplied with 1/8" internal thread connections. This Meter's index is standard roller counters showing a reading to 0.01 Litres.

Pulsed versions of each Meter are available that provide remote communication and easier Meter reading to a Building Management System or other local data logging facility. The HZ3RR and HZ5RR are virtually the same design with the addition of a pulse block onto each Meter. A visual reading can still be taken from these models as well.
