Mechanical energy- or heat-meter for liquid or gas - uses purely mechanical units relying on vol. or shape changes caused by heating

摘要

The mechanical energy of heat meter for liquid or gas without auxiliary power contains only purely mechanical units whose different metering relies on vol. or shape changes caused by heat. The readout of the energy consumed can be achieved by subtracting the indications before and after the energy or power load. Alternatively, the readout can be direct using an indicator with a compensation transmission. USE/ADVANTAGE - For metering use of radiators etc. in central heating systems. Records actual energy rather than fluid flow. Maintenance free, relatively accurate and easily read.
