ProMinent's controllers and sensors

With ProMinent's controllers and sensors.

What do you expect from your controllers and sensors?

We expect accuracy from our controllers and sensors. We demand reliability. We believe our sensors and controllers should be compatible with your existing setup, but also integrate flawlessly with our entire product lineup. And we expect them be to economical.

If we had to choose one word to describe our expectations from our products, we would say we expect nothing less than perfection. Read more about our sensors, our controllers, and how well they work together.

Industry-leading measurement

with industry-defining sensors

Our wide range of amperometric and potentiometric sensors allows exact registering of the concentration for almost any metering task. Paired with our controllers, you have precise control over every aspect of the initial water and chemical treatment process.

A large range of suitable fittings leads to the possibility of tailor-made and easy integration of the sensors into your process, meaning you don’t have to change anything else about your existing setup.

We offer sensors for the following variables:

Game-changing controller technology

ProMinent's control technologies for fluid metering are part of our "intelligent metering" process. Using the right control technology can help to substantially optimize metering of fluid chemicals. It can increase process safety, result in cost-savings for metering-chemicals and the disposal of metering-chemical-surpluses, as well as providing the transparency of the measuring data in real time.


The PCM is a complete measurement and control package. Built so that it is plug and play, the PCM is available in a wide variety of flexible configurations. Complete with sensors, controllers, and the required PVC valves, the PCM is ProMinent’s wall-mountable, no-fuss control and monitoring unit.

Dulcometer DACa

The multi-parameter measuring and control device offers special functions for water treatment, such as the processing of variables and control parameter switching (in real time and controlled by event), an external setpoint setting via mA signal. The new controller platform from ProMinent was developed to continually measure and control the parameters required, and can be configured for two or three measuring channels. Sensors from 14 freely selectable measured variables can be connected per channel. The measurement and control device can communicate with analogue or digital sensors and actuators.

See the DACa's specifications.

Dulcometer Compact

for pH or ORP control

The ProMinent Duclometer Compact analyzer provides precise measurement and control of pH or ORP process variables. The pre-configured Compact can be programmed for either pH or ORP control without having to purchase a separate analyzer. Temperature compensation for pH can be added using an optional PT 1000 sensor. The Compact comes standard with pulse relay for pump control, configurable analog output and configurable power relay.

See the Compact's specifications.

The ProMinent Aegis controller is the perfect economical solution for process cooling, boiler and waste water treatment applications that provides the latest in controller technology. It features variable frequency pump controls, allowing precise chemical feed using the accuracy of pulse outputs rather than turning pumps on and off. Aegis provides real time information on data logging using our exclusive Web Browser Ready Trackster Software. And our exclusive Thermal Flow Switch design does not require user adjustment or calibration, and operates on 1 GPM flow rate with no moving parts.

See the AEGIS's specifications.
