GasMeter Elster Type QA160

Turbine gas meter / flow meter gas

Selama pengukuran, molekul gas cenderung berjalan melalui meteran secara terus menerus, yang menghasilkan denyut selama kalibrasi. Peredam suara dapat digunakan untuk menghindari kesalahan pengukuran yang signifikan.Sistem roda gigi, roda turbin, bagian ekstrusi, dan unit rumah tertutup adalah komponen utama meter turbin.

Saat gas mengalir, roda turbin mulai berputar. Putaran roda turbin sebanding dengan kecepatan aliran. Oleh karena itu, volume gas dapat dihitung sehubungan dengan putaran roda.

Deskripsi

Brief information GasMeter Elster Type QA160

Elster-Instromet quantometers are highly reliable gas meters, which can be used
throughout the entire fi eld of fl ow metering and which fulfi l 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 fl owing 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.
On account of the proven metering principle and the quality of the materials in use, the
quantometers meet the highest standards. By using the quantometers in production and
heating processes, it is possible to control the fl ow of gas precisely and therefore optimise
the use of energy.
The QA quantometers are fi tted 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 fl ow 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 specifi c part of the building or
for any cost centre at any chosen time.
Installation tips: 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. A fi lter must be connected in the inlet pipe, provided that the gas fl ow
is not free of foreign bodies and dust. The position of the installation can be selected as
required.
The fl ow direction is clearly marked by an arrow on the meter housing.
Interfaces/Outputs: – QA: E1 Reed switch
– QA/QAe: E 200 Namur output
(in accordance with DIN EN 50227)
– QAe: Optical interface in accordance with EN 1434-3
(ZVEI- compatible)
– QAe: M-BUS interface in accordance with EN 1434-3
(Bus voltage approx. 40 V DC)
– QAe: L-BUS interface
(Bus voltage approx. 3.6 V DC,
open collector output)
