Control Modules

Modules CM2, CM4 and PCIM4

Porter Instrument's Control Modules are designed for use with Porter's Mass Flowmeters and Flow Controllers. Models CM2 (two channel), CM4 (four channel) and PCIM4 (four channel) provide operating voltages, setpoint control (for flow controllers), and an LED display. Both process flow rates and channel setpoints are indicated on the display as a percentage of full scale. Setpoints are adjustable to any value in the range using the 10-turn adjustment controls.

All three models feature the Automatic Proportional Tracking (APT) mode. APT operation permits controlling the flow rate in one or more channels as a fixed ratio of the flow rate in a reference channel, and allows the slave (secondary) channel(s) to track any change in the reference channel flow rate. Additionally, the Model PCIM4 includes Porter's exclusive COM-LINK feature, a two-way computer interface communicating link.
