Introduction

In designing the MULTICAL® 601 we have attached great importance to flexibility via programmable functions and plug-in modules (see chapter 10) in both the calculator top as well as in the base unit to ensure optimal use in a large number of applications. In addition, the construction ensures that already installed MULTICAL® 601 meters can be updated via the PC program METERTOOL.

This technical description is prepared to give managers, meter electricians, consulting engineers and distributors the possibility of utilizing all functions available in the MULTICAL® 601. Furthermore, the description is made for laboratories for the testing and verification process.

During the preparation of this technical description we have drawn attention to the functional differences in changing from MULTICAL® type 66-CDE into MULTICAL® 601 to secure a safe product conversion for existing users.

At each relevant paragraph that refers to this product conversion there will be comments marked as follows: 66-CDE ⇒ MC 601


 

MULTICAL® 601 is a thermal energy meter with many applications. In addition to being a precise and reliable heat meter for battery or mains operation, MULTICAL® 601 is also used for:   Cooling measurement in water-based systems  Bifunctional heat/cooling measurements in separate registers  Leak surveillance of hot and cold-water installations  Power and flow limiter with valve control · Data logger  Data communication  Energy measurement in open systems    Approval PTB 22.52/05.04, PTB 22.55/05.01, TS 27.01/155 Standard EN 1434:2004 and OIML R75:2002  EU directives Measuring Instrument Directive, Low Voltage Directive, Electromagnetic Compatibity Directive  Temperature range θ: 2°C?80°C Differential range ΔΘ: 3 K?70 K Accuracy EC ± (0.5 + ΔΘ min/ΔΘ) % Temperature sensors -Type 67-A Pt100 - EN 60 751, 2-wire connection -Type 67-B og 67-D Pt500 - EN 60 751, 4-wire connection Temperature sensor Type 67-C Pt500 - EN 60 751, 2-wire connection Compatible flow sensor type Compatible flow sensor types -ULTRAFLOW®  -Electronic meters with an active 24 V pulse output  -Mechanical meters with an electronic pick-up unit  -Mechanical meters with a Reed switch  Flow sensor sizes [kWh] qp 0.6 m3/h…15 m3/h [MWh] qp 0.6 m3/h…1500 m3/h  [GJ] qp 0.6 m3/h … 3000 m3/h  EN 1434 designation Environmental class A and C
