We have increased our range of Qa series gas meters to now include the scre

Elster-Instromet quantometers are highly reliable gas meters, which can be used throughout the entire field of flow metering and which fulfil all of the varying requirements of industrial metering. The QA and QAe quantometers work on the principle of the rotating turbine wheel. The rotation of the turbine wheel is proportional to the volume of the flowing gas and this volume (Vb/m3 ) is registered by either a mechanical (QA) or an electronic (QAe) totalizer. Self - lubricating bearings ensure that the quantometers operate completely without any maintenance. By using the quantometers in production and heating processes, it is possible to control the flow of gas precisely and therefore optimise the use of energy.


• Compact gas meter
• Meter sizes QA/e 10 - QA/e 1000
• Flow ranges 1.6 - 1600 m3/h
• Measuring range up to 1:20, at higher pressures up to 1:50
• Nominal width DN 25 - DN 150
• Aluminium housing
• Temperature ranges QA: - 10 °C up to +60 °C, QAe: 0 °C up to +50 °C
• Maintenance - free
• QA: protection class IP52
• DVGW approved

The QA quantometers are fitted with a 7 - digit mechanical totalizer which registers the volume Vb in cubic meters (m3). The QAe quantometers are equipped with an electronic totalizer. Besides the normal registration of the total volume (Vb, m3 ), the QAe can also display the flow rate (Qb, m3/h), the volume of a key - day (m3 / Vb on the key - day) and the date of the key - day. This means that the user can easily calculate the gas consumption for any specific part of the building or for any cost centre at any chosen time. The Elster - Instromet quantometers can be installed easily in the straight pipeline. The inlet pipe should be 3 x DN, the outlet pipe should be 2 x DN in nominal size of the meter. The flow direction is clearly marked by an arrow on the meter housing.
