Endress+Hauser Liquiline CM14: Compact Memosens Transmitter for Liquid Analysis

Endress+Hauser Liquiline CM14 Memosens liquid analysis transmitter

A straightforward measuring point for everyday liquid analysis

The Endress+Hauser Liquiline CM14 is a compact four-wire transmitter for installation in panels or control cabinets. With one digital Memosens sensor input, it provides a practical platform for pH/ORP, conductivity or dissolved oxygen measurement in water and wastewater applications.

Liquiline CM14 is designed for standard measuring points where clear local indication, dependable signal transmission and easy operation are priorities. Memosens hot plug-and-play technology enables rapid sensor installation and configuration, while precalibrated sensors can help reduce work at the measuring point.

Why Choose Liquiline CM14?

Compact panel format
The 48 × 96 mm front format fits common cabinet cut-outs and keeps control panels organized.
Digital Memosens input
Hot plug-and-play sensor recognition supports fast commissioning and active indication of cable breaks.
Useful standard outputs
Two current outputs and two relays support the main process value, temperature and limit-control tasks.

Selection and Installation Notes

CM14 is supplied in measurement-specific versions, so the transmitter must be matched to the required parameter and compatible Memosens sensor. Check the cabinet cut-out and built-in depth, power supply, output scaling, relay functions, sensor cable length and environmental conditions. For hazardous-area installations or multi-channel systems, select a transmitter designed for those requirements.

Information Needed for Correct Selection

  1. Required parameter: pH, ORP, conductivity or dissolved oxygen
  2. Medium, measuring range, temperature and process conditions
  3. Preferred Memosens sensor and assembly
  4. Power supply and 0/4–20 mA output requirements
  5. Relay functions, alarms and panel installation details
