pH/ORP transmitter
Liquisys CPM253
Compact field device for all industries
Liquisys CPM253 is a standard pH/ORP transmitter for all analog and digital Memosens sensors. It improves your operational safety thanks to continuous plausibility, process and sensor checks. Select from numerous hardware and software modules, such as relays or fieldbus communication, to adapt it exactly to your measuring task. This modularity also allows you to upgrade the transmitter at any time. A simple menu and two-point calibration make configuration and operation fast and easy.

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.Competence Brochure (CP)04/11English -
