Elster Instromet turbine meters as well as quantometers are flow meters which display the volume flowing through the device in actual cubic meters. The incoming gas is accelerated through the inlet body and strikes the blades of the turbine wheel. The revolutions of the turbine wheel are transferred to an 8-digit roller counter via a multistage gear and a magnetic coupling.
Turbine meters TRZ2 and SM-RI-X are approved for official metering and billing purposes (custody transfer) of natural gas in gas transmission and distribution as well as with a variety of technical gases in industrial applications. Quantometers are short pattern turbine meters, They are preferably used in non-custody transfer applications (i.e. in-plant measurement).
All turbine gas meters fulfil international directives and norms for pressure equipment (PED) and explosion protection (ATEX) as well as metrological requirements and directives.
Q-Quantometer
The flanged housing of the Q Quantometers is made of spheroidal graphite iron, cast steel or welded steel, depending on the pressure rate. The Q Quantometers are available in a variety of diameters and pressure ratings.

Q75 - Quantometer
The high performance is subscribed by the fact that the Q75 series is approved for fiscal metering in a number of countries. The series offers a large variety, from cast body to spool piece, sizes up to DN 750 / 30", and a multitude of options, from lubrication systems to high frequency output.

QA i QAe - Quantometer
The wafer type housing of QA and QAe (with electronic totalizer) is made of aluminium. Depending on the version, the volume is displayed on a mechanical (QA) or an electronic totalizer (QAe). QA and QAe Quantometers combine the high accuracy of the Q series of Quantometers with low weight. The Quantometers are available in a number of flow ranges, diameters and pressure ratings. Depending on the ...

SM-RI-2
The new generation SM-RI-2 is the first gas turbine flow meter that provides two-way metering. Although the flow rate increased, due to the competition with the existing ultrasound meters, the pressure drop is at the level of half pressure drop of the conventional turbine meters.

TURBINSCOPE®
This unique diagnostic service is used to examine turbine meter performance under real operating conditions. The basic requirement for this service is the availability of one high frequency probe from the turbine rotor of the meter. Data is collected on-site and is analysed at the factory to determine meter and installation conditions. Possible outcomes of these analyses include discovering ...
