1 Safety instructions

Safe operation of the device is only guaranteed if the Operating Instructions have been read and

the safety instructions they contain have been observed.

1.1 Designated use

The BTU meter is a device for measuring energy flow in heating and cooling systems. The

linepowered arithmetic unit can be used universally in industry, long-distance heat and building

systems.

• The manufacturer cannot take responsibility for any damage caused by misuse of the device.

It is not permitted to make any changes or reconstruction to the device.

• The device may be operated in built-in state only.

1.2 Installation, commissioning and operation

The device is safely manufactured using state-of-the-art technology and complies with the

respective regulations and EU Directives. The device could be dangerous if it is incorrectly

installed or used.

Installation, wiring and maintenance of the device must be carried out only by trained, skilled

personnel authorized to perform such work and instructed by the facility's owner-operator. The

skilled personnel must have read and understood these Operating Instructions and it is mandatory

for them to follow the instructions they contain. The operator must ensure that the measuring

system is correctly wired in accordance with the wiring diagrams. When the housing cover is

removed, the shock protection is disabled (danger of electrocution). The housing may be opened

by trained skilled personnel only.

The device may be operated in built-in state only.

1.3 Operational safety

Technical improvement

The manufacturer reserves the right to improve and update the technical details. For details of

improvements or additions to these instructions, please contact your local sales organization.

1.4 Return

For a return, e.g. in case of repair, the device must be sent in protective packaging. The original

packaging offers the best protection. Repairs must only be carried out by your supplier's service

organization.

When sending in for repair, please enclose a note with a description of the error and the

application.

1.5 Notes on safety conventions and icons

The devices are safely manufactured and tested using state-of-the-art technology and have left

the factory in safety-related flawless condition. The devices comply with the respective

regulations and EU Directives. The devices could be dangerous if incorrectly installed or used.

A0013584

å 2 Labeling of front foil for devices with approval for custody transfer

2.2 Scope of delivery

The scope of delivery of the BTU meter comprises:

• BTU meter (field housing)

• Brief Operating Instructions in paper form, Operating Instructions and additional

documentation (on CD-ROM)

• Optional temperatur sensors TR10

• Optional interface cable and DVD set with FieldCare Device Setup parameter configuration

software

• Optional Field Data Manager software MS20

• Optional mounting hardware for top-hat rail, panel mounting, pipe mounting

• Optional overvoltage protection

Please note the device accessories in Section 8 ’Accessories’ of the Operating Instructions

on CD-ROM.

2.3 Certificates and approvals

The BTU meter and the optionally available paired temperature sensors fulfill the requirements

of Directive 2004/22/EC (Measurement Instruments Directive, MID) and OIML R75 and

EN-1434.

If the arithmetic unit with temperature sensors is to be used in commercial applications, the flow

sensor must also have a type approval (incl. conformity assessment) according to MID.

Measuring devices with MID approval have the MID mark on the front foil. ((® å 1, ä 5)).

This approval replaces the initial calibration on-site.

On request, the calibrated arithmetic unit is shipped from the factory preset, but can also be

adjusted individually on-site. Custody transfer-related parameters, such as the pulse value of the

flow transmitter, can be changed up to three times. The changes to the custody transfer-related

parameters are recorded in a custody transfer logbook. This allows individual defective sensors

to be replaced in the field without losing the custody transfer status.

The device also has a national approval as a BTU meter for cooling or for combined heating/

cooling applications. The initial calibration of these devices is always carried out on-site by a

calibration officer.

CE mark, declaration of conformity

The device is safely built and tested according to state-of-the-art technology and has left the

factory in perfect condition as regards technical safety. The device meets the relevant standards

and directives as per EN 61010-1 "Safety requirements for electrical equipment for measurement,

control and laboratory use".

Thus, the device described in these Operating Instructions meets the legal requirements of the

EU Directives. The manufacturer confirms successful testing of the device by affixing to it the

CE mark.
