Kamstrup MULTICAL® 6M2 Installation and User Guide

  • Hello! I'm a chat assistant and I've analyzed the Installation and User Guide for the Kamstrup MULTICAL 6M2 energy meter. This document describes how to install and use the device including details on mounting procedures for sensors, connection guides for different types of flow sensors, and setup instructions for using modules, power options and various communications protocols. I'm ready to help you with your questions regarding this document or the MULTICAL 6M2 meter.
  • Can the temperature sensor cable length be changed?
    What type of fluid is the MULTICAL® 6M2 compatible with?
    What voltage options are available for powering the calculator?
    What kind of communication modules are compatible with this meter?

3.2 GWF flow sensor
GWF volume mesuring meers cn wihsnd insllions where nifreeze gens re presen.
The mesuring dynmics re, however, influenced depending on he concenrion. Wih n
nifreeze concenrion:
1 Below 5 % here is no influence on he mesuring dynmics
2 A 30 % he qi vlue is doubled.
Noe: The qi increses beween 5-30 %. This degrdion kes plce proporionlly.
3 Above 30 % we do no recommend hese meers.
3.2.1 Mouning of GWF flow sensor
Single je meers (Unico®) cn be inslled
in horizonl or vericl pipelines. Horizonl
insllion is preferred since i offers superior
mesuring dynmics.
Muli je meers (MTH) cn only be inslled in
horizonl pipelines. The meer ype ple mus
lwys fce upwrds.
I is recommended o insll shu-off vlves
before nd fer he meer, o fcilie he
insllion nd removl of he meer for
periodic inspecion nd minennce work.
Py enion o he direcion of flow when
inslling he meer. An rrow on he meer
body indices he direcion of flow.
Noe: The meer should be proeced gins mechnicl jols or vibrion, which could be presen
in he insllion.

10.2 Communicion op module
10.2.1 Type 602-0C: 2 pulse oupus for CE nd CV
This op module hs wo configurble pulse oupus, which
re suible for volume nd energy pulses for he meers,
cooling meers nd combined he/cooling meers.
The pulse resoluion follows he disply (deermined by he
CCC code).
E.g. CCC=119 (qp 1,5): 1 pulse/kWh nd 1 pulse/0.01 m3.
The pulse oupus re opoisoled nd wihsnd 30 VDC nd
10 mA.
Normlly energy (CE) is conneced o 16-17 nd volume (CV)
o 18-19, bu oher combinions cn be seleced by mens
of he PC progrm METERTOOL HCW, which is lso used for
selecing he pulse durion  eiher 32 or 100 ms.

10.3 Communicion bse modules
10.3.1 M-Bus + pulse inpus, ype 67-00-20/27/28/29
M-Bus cn be mouned in sr, ring or bus opology. Up o 250 meers cn be conneced
depending on he M-Bus Mser’s power supply nd he ol cble resisnce.
Cble resisnce < 29 Ohm
Cble cpciy < 180 nF
The M-Bus nework is conneced on erminls
24 nd 25. The polriy is unimporn.
M-Bus comes wih pulse inpus.
10.3.2 LonWorks + pulse inpus, ype 67-00-24
See installation instructions 5512-396 (DK) or 5512-403 (GB).
10.3.3 BACne® + pulse inpus, ype 67-00-66
The BACne® module communices wih BACne® on MS/TP vi RS-485 s  mser/slve or
slve device.
The BACne® module rnsfers  number of boh cul d s well s ccumuled d.
Furhermore, info codes for generl lrm, flow error, emperure error, wer lekge, pipe burs,
ir in sysem, nd wrong flow direcion cn be rnsmied o he BACne® Conroller.
The wo pulse inpus llow connecion nd reding of wo ddiionl meers for e.g. wer nd
elecriciy wih pulse oupu.
10.3.4 Modbus RS485 RTU* Slve Module + pulse inpus, ype 67-00-67
The Modbus bse module for MULTICAL® ensures  simple inegrion of Kmsrups he,
cooling nd wer meers ino Modbus bsed sysems. Modbus is n open, widespred nd well
esblished seril communicion proocol used wihin building uomion.
