Integrated service unit Combi module M-bus and …

1 Combi module M-bus and pulsesThis module is used if the ULTRAHEAT 2WR5 is connect-ed to an M-bus system and simultaneously has to passon pulses to systems or district heating controllers forlimitation and control. Combi module for pulses and 20-mA current loopThis module is a combination of a 20-mA module anda pulse module . Modem moduleIntegrated analogue modem without separate supply,can be called and can call itself, password protection, and Universal The ULTRAHEAT 2WR5 Heat MeterIntegrated service unitThe 2WR5 features an Integrated service unit noadditional equipment is required.

2 The extensive self-diagnostics facilitates rectification of any problemswith the unit or is standardThe standard meter is already equipped with an opticalinterface for communication and can be read or pro-grammed via a PC or hand-held terminal. As an optionit is possible to expand the unit with reaction-freemodules. The 2WR5 automatically detects whichmodule is plugged in. Adaptations in parameterizationare therefore not module (current loop):This module allows you to read the heat meter with ahand-held terminal or a PC via a cable up to 100 m inlength (front gate reading).

3 M-bus moduleUp to 250 heat meters can be connected in a networkvia a 2-wire cable using this module and read from acentral moduleThis module contains either two pulse outputs that areelectrically isolated from the heat meter one forenergy and the other for volume , or status informa-tion, to control rolling mills, or one fast pulseoutput, to control closed-loop controllers. Withthe higher pulse rates, a distinction is made betweentypes of pulses (linear/scaled), pulse duration, and thequantity transferred.

5 We supply the ULTRAHEAT 2WR5 for allcommon nominal flow rates from to 60 m3/h andthe associated mounting approvalThe ULTRAHEAT has Europe-wide approvaland complies with the stringent ENrequirements 1434 Class 2. It thereforemakes a contribution to confidence inheat billing and avoids the expenseof dealing with meter to operateWhatever the volumes to bemeasured the electronics andthe measurement principle andtherefore operation are alwaysthe same. That makes for morereliable handling.

6 It is also pos-sible to read out data or makesettings easily via a hand-heldterminal or PC. The optical in-terface is used for that ULTRAHEAT also featuresself-monitoring. It provides earlywarning if the heating water iscontaminated. Standard mountinglengths and flow rates also permitsimple replacement of old to runLong life, minimum failure rate, measurement stabilityand dynamics all these features make this heat meterso economic to run. And accurate quantity measure-ment even for the lowest consumption brings addition-al revenue to our customers.

7 The low pressure lossreduces the pump power. That means lower powerconsumption and fewer protected investment way into the futureThe communication modules make systemintegration possible: All modules can be addedsubsequently without a negative reactionand during operation. Functions liketariffs or the low-energy house permitfuture billing variants of the energy you can rely onLike its predecessors, the ULTRAHEAT2WR5 measures absolutely accurately andstably for many years.

8 This has been prov-en by numerous tests on random sam-ples in various countries and in tests byindependent bodies. Its wear-free methodof operation and use of robust materialsensure a long life. And the newULTRAHEAT 2WR5 is the only heat meterin the world whose volume measuring unitis made of pure metal even for small flowquantities (qp = to ). Plastic parts havebeen eliminated.[[[Flow rangeThe mounting lengths correspond to the standarddimensions of vane-type meters simple replacementis ensured.]]]

9 In addition to the permanent temperatureof 130 C, an overtemperature of 150 C is permissiblefor up to 2000 hours. Commissioning work, failures, andfast heating are therefore no pressure lossThe pressure loss on the ULTRAHEAT 2WR5 is muchlower than in conventional vane-type meters and isway below 200 heat meter can be mounted both vertically andhorizontally filters or straight inlet and outlet sectionsare not required. The straight measuring tube keepsthe pressure loss low and prevents the accumulationof air and electronic unit can be mounted on the tube itselfor separately on a 2WR5 Technical dataValid for Germany only.
