Multi-protocol heating and cooling energy calculator EM 6000

Characteristics

  • Heating and cooling meter and combined functions
  • MID or PTB K 7.2 approval (optional)
  • Pulse-, frequency- and analogue input
  • indivual setup of communication interfaces
  • M-Bus Interfaces to building control systems
  • Highly accurate temperature measurement from -50 to +550 °C with PT100 sensors or temperature transmitters with 0/4 - 20 mA
  • Calculation functions: heat energy (enthalpy differential), volume, mass, power, flowrate, density, K-factor, temperature difference
  • Up to 12 registers for tariffs
  • List of common heat transfer fluids
  • Programmable specific heat transfer fluid is possible

Basic function and measuring principle A so-called ?combined? heat meter requires the following individual elements:
  • 1 x pair of temperature sensors
  • 1 x volume-metering element with pulse generator
  • 1 x transducer (counter mechanism)
Customer advantages:

  • Long-term measuring stability
  • Versatile
  • Ideal for building control systems
  • Economical integration and high transparency
  • Cost savings by reverification as no electrical installation work required
  • Smallest measurement deviations also with cooling media
  • Economical installation
  • Extendable with add-on modules

Application:
Top quality heat and cooling meters for heating, air-conditioning, cooling and solar energy plants can be realised with the CALEC®ST II energy calculator. The modular unit distinguishes itself by its long-term stability. Flexible communications makes it particularly interesting for integration into building management systems.

Application:
The CALEC®ST II is used for energy metering in split configuration with passive impulse-generating volume-measuring elements and Pt100 temperature sensors in two- or four-wire version. In most cases, CALEC®ST II is used with the following volume-measuring elements:

  • Multibeam meters in the range Qp 0.6 - 10 m3/h
  • Hydrometric vane in the range Qp 15 - 400 m3/h
  • Static volume-measuring elements up to Qp 400 m3/h

Choose from our wide range of volume-measuring elements. Our advisers will be pleased to help you select the right ones for your needs.

Obligatory calibration and type-approval:
In most countries energy metering systems used for commercial purposes are subject to compulsory verification. The devices comprising the metering system must all possess official pattern approval. CALEC® ST II has been approved according to both the european Measuring Instruments Directive 2004/22/EG and the national PTB 7.2 directive for cooling meters. (The pattern approvals are limited to the use of water as a heat carrier.) Officially verified heat meters must be reverified before the verification period has expired. The operator is responsible for compliance with this requirement. (Re-)Verification includes all parts (temperature and flow sensors, calculator) forming the complete heat meter. The plugin calculator module considerably reduces the cost of reverification since there are no wires to be disconnected. For testing and reverification purposes a high resolution display mode as well as CALEC® Win are avaiable (as download from www.aqua-metro.com ). New: Commissioning of officially verified devices is even easier as both the pulse value and the installation side can now be programmed in situ.
