Kamstrup MULTICAL® 402 Installation and User Guide

  • Hello! I've reviewed the Installation and User Guide for the Kamstrup MULTICAL 402 cooling meter. This document covers everything from initial setup and mounting of the device to more specific configuration details, such as using plug-in modules for advanced communication. I am familiar with its features, like various power supply options or the info codes for troubleshooting, and I'm ready to answer your questions about it.
  • Can the temperature sensors be separated?
    What type of temperature sensors does MULTICAL® 402-T require?
    What are the mounting options for the flow sensor?
    What kind of power supply does the device use?
