Pressure Test Point; Temperature Test Points - Elster Instromet RVG Manual De Instrucciones

12. Pressure Test Point

A straight male coupling in accordance with DIN 2353 is pre-fitted on the meter housing for
connection of a pressure sensor for instance.
The pressure test point is marked p
in accordance with DIN EN 10305-1 (e.g. steel grade E 235).
Important: Do not connect the straight male coupling to pipes made of stainless steel or
pipes made of nonferrous materials.
Note: We recommend that you use original Parker-Ermeto pipe unions only. Functional
safety and reliability are ensured only if the material combination of the union component and
the pipe are intermatched. We recommend that you contact our Elster-Instromet Customer
Service (Tel. +49 (0)6134-605-0 / -346) for conversion work and when installing additional
devices.

13. Temperature Test Points

You can use a maximum of two temperature sensors
for measuring the gas temperature in the meter
housing
(Series RVG EBL67, Ident. No. 73013525),
(Series RVG-ST EBL45, Ident. No. 73013410).
Note that temperature measurement on measuring
systems in the open air may be influenced by the
ambient temperature. For this reason, the metering
elements outside the pipe should be adequately
insulated against ambient temperature influences. In
order to achieve optimum thermal conduction, also
fill the thermowell(s) with a heat-conductive fluid or
paste.
If no temperature test points in the meter housing are planned, measure the temperature
in the pipe upstream of the rotary gas meter at a distance of up to 3 x DN.
