1-channel transmitter
Liquiline CM14

Compact panel device for the food, power, water and wastewater industries

Liquiline CM14 is a basic transmitter that offers all that you need to run a standard measuring point. It fits in the common cabinet cut-outs and is easy to commission thanks to Memosens digital technology. The Memosens hot plug and play concept allows you to quickly install and configure your digital pH/ORP, conductivity or dissolved oxygen sensors. Liquiline CM14 is compact, easy-to-operate, and cost efficient.

Measurement and control aspect of pH using inductively coupled with bidirectional Memosens technology in flue gas desulfurization process
White Paper CP971C pH measurement and control in a power utility is an
integral part of process. The scrubber efficiency is highlydependent on
the pH. Numerous opportunities were revealed for saving time, as well as
the cost and materials in power plants. In afossil fuel power plant,
the
chemical energy stored in coal, oil, natural gas, shale oil, oxygen and
air
is converted into thermal, mechanical and finally into electrical
energy. In
other words, water is heated to steam, which spins a steam turbine. The
steam turbine drives an electrical generator.
