1. General This guide is intended for trained specialized personnel. For this reason, no basic working steps are included. The meter tamper-evident seal must not be damaged! A damaged seal will result in immediate invalidation of the factory warranty and verification or declaration of conformity.
2. Transport and storage Unpacking Energy meter are measuring devices and must be handled with care. To protect against damage and soiling, they should only be unpacked immediately prior to installation. Transport The transport of the meter is permitted only in the original package. When sending wireless measuring instruments / components by air, deactivate the wireless before shipping.
When choosing the installation location, make sure that the meter is perfectly accessible for service and operating personnel. It is recommended that shut-off valves are fitted before and after the meter to simplify removing the meter. 3.1 Preparatory work ▪ Rinse the conduit thoroughly. ▪...

3.2.2 Requirements of straight-line sections Flow metering section DN15…50 does not require to have straight sections before and after of flow sensor. Installation after the valve at a distance shorter than 5D without straight sections prohibited (fully Installation at the highest point of the system is opened full-bore ball valve excluded).
3.3.1 Mounting RTD 1 – temperature sensor; 2 – Temperature sensor holder; 3 – Sealing ring For DN15…40 T1 pre-installed into flow sensor pipe (see figure): T2 should be installed in specialized fittings for DN15…25 with a thread for connecting RTD. Installation into such fittings does not require additional sealing.

For DN greater than 50 installations of both RTD is carried out by means of a protective sleeve (pos.3), fig. below If temperature sensor t1 has to be installed separately (not inside flow metering section), orifice in the flow metering section must be plugged with a blind plug from the delivery set of the meter. 1 –...
4. Communication 4.1 M-Bus wired A 2 pin M-Bus line lead out of the housing. Connect the M-Bus line with the marked connections of the M-Bus Master. Here it concerns a serial interface for communication with external devices (M-Bus control centers), ▪...
6. Maintenance Flow sensor and temperature sensor may not be disconnected from the integrator. After repair work, perform recalibration in an accredited testing agency. Information concerning reconditioning or maintenance can be found in the processing concept (this will be made available for laboratories and testing agencies upon request). 7.
