9 HEAT FLOW
9.1 Overview
9.1.1 Benefits of Steam/Hot Water Flow Metering
The purpose of steam/hot water flow metering is to measure the amount of steam or hot water which is
being produced, and to check the amount of heat this is delivering. The majority of plants will require
steam flow metering to check how much steam is being generated and used, and at what cost, so the
overall plant efficiency can be determined.
Steam flow meters are very expensive to purchase and install, however with the Autoflame system, the
simplest form of steam or hot water flow metering can be set with just using the default values.
Autoflame has been granted a worldwide patent on the steam/hot water flow metering function in the
software.
9.1.2 Configuration
To activate steam or heat flow metering on the Mk8 MM, the Heat Flow software feature must be
unlocked. The activation code for the serial number of the MM will need to be purchased using part
number MK8009, and uploaded to the unit via Download Manager software.
Please see Autoflame PC Software Guide for more information on unlocking expansion features on the
Mk8 MM using Download Manager software.
