The Liquiline Compact CM72 transmitter is small and lightweight and is used together with Memosens digital sensors. It is the right choice for applications with limited installation space where multiparameter devices are not required. Combined with a sensor, it can be installed in most assemblies for even more convenient installation. The CM72 is ordered with preconfigured measuring parameters and measuring range, so it can be used directly after installation, with high safety and no operating errors.
Advantages
Small installation space required: the two-wire device can be installed inside the assembly without its own power supply.
Fast start-up: the CM72 has fixed settings, requires no commissioning and can be put into service quickly.
Full benefit of all the advantages of Memosens digital sensor technology: Memosens digital sensors provide the most secure data transmission, the highest measured value stability and are very convenient to use.
On-site diagnostics: red/green LED indicators show the status of the transmitter and the connected sensor.
Suitable for all installation positions: the CM72 transmitter is always the right choice, even if the measuring point has to withstand dust, water vapor, rain, snow, heat or extreme cold directly.
Application areas
The Liquiline Compact CM72 can be used in all industries and their utilities and allows connection of all sensors with a blue Memosens plug.
pH electrodes
ORP electrodes
Conductivity sensors
Dissolved oxygen sensors
Disinfectant sensors
The measuring parameters and measuring range are preset when the transmitter is ordered and cannot be changed later.
The two-wire instrument is equipped with the following interfaces:
4...20 mA
With numerous international explosion protection approvals, the CM72 can be used in hazardous areas, e.g. IECEx, ATEX and CSA.

Municipal Wastewater Treatment · multiparameter — Application Case
Application Context
the inlet, biological and outlet stages of a municipal plant is a typical Municipal Wastewater Treatment duty. The project started from multiparameter, focusing on monitoring several water parameters at one measuring point.
Process Constraints
effluent parameters drift and probes foul with sludge and biofilm, and high solids and corrosive fractions, with large diurnal flow swings only amplify it. The multiparameter specification must therefore cover configured by parameter set, mounting and cleaning needs.
Delivery Approach
Delivery was handled as the analyser range — selecting as part of a complete water-analysis system. Execution centred on configured by parameter set, mounting and cleaning needs, together with stable compliance with Grade 1A discharge limits and online data reporting.
Field Results
Operation shows the benefit clearly — one point replacing several single-parameter units, saving capex and upkeep, with confidence in this measuring point improving markedly.
Food & Beverage · multiparameter — Application Case
Customer Profile
The typical setting in Food & Beverage is dosing, pasteurising, filling and CIP stages. The measuring point is multiparameter; the focus is monitoring several water parameters at one measuring point.
Key Difficulties
Conditions are syrups, dairy and beverages that scale easily, under strict hygienic requirements and, on top of that, frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles, which a standard configuration cannot handle for long. The design therefore starts with configured by parameter set, mounting and cleaning needs.
Implementation
The scope ran through the analyser range: selecting as part of a complete water-analysis system. Technically it hinges on configured by parameter set, mounting and cleaning needs, and on these requirements: food-safety and hygienic design per 3-A / EHEDG.
Customer Benefit
In practice this means one point replacing several single-parameter units, saving capex and upkeep, which cut the workload on the site maintenance team.
Chemical & Pharmaceutical · multiparameter — Application Case
Project Background
The project covers reactors, metering vessels and finished-product tanks. The work centres on multiparameter and the core task is monitoring several water parameters at one measuring point.
Operating Challenges
The medium and duty are characterised by highly corrosive media with solvents and crystallisation, partly in explosive atmospheres, and corrosion plus Ex protection shortens instrument life and makes downtime costly. So multiparameter cannot be specified generically — it calls for configured by parameter set, mounting and cleaning needs.
Solution
The Ainstru engineering team worked through the analyser range: selecting as part of a complete water-analysis system. The configuration involves configured by parameter set, mounting and cleaning needs, with these requirements in view: Ex certification and GMP traceability of records.
Results
Since start-up the system has run steadily; the practical result is one point replacing several single-parameter units, saving capex and upkeep.
Power & Energy · multiparameter — Application Case
Project Overview
The site is boiler feedwater, turbine condensate and FGD/DeNOx systems. The customer wanted multiparameter properly configured on the existing plant, with the aim of monitoring several water parameters at one measuring point.
Technical Challenges
What actually causes trouble is high temperature and pressure with both steam and saline water, and drift under high temperature and pressure, with very costly unplanned outages. All of this means the multiparameter configuration has to involve configured by parameter set, mounting and cleaning needs.
Configuration
Supply and installation were organised through the analyser range: selecting as part of a complete water-analysis system. On site this meant configured by parameter set, mounting and cleaning needs, checked line by line against: compliance with power-industry codes and unit availability targets.
Performance
After commissioning the outcome is one point replacing several single-parameter units, saving capex and upkeep, and the readings are now used for process tuning.
