We describe the use of measuring and control technologies for fluid dosing as “intelligent dosing”. Using the right measuring and control technology can help to substantially optimize metering of fluid chemicals.

The use of the right measuring and control technology grants a list of advantages for the dosing of fluid chemicals:

- Increased process safety
- More efficient process guidance (e.g. increase in product quality)
- Cost-savings for dosing-chemicals
- Cost-savings for the disposal of dosing-chemical-surpluses (effluent costs!)
- Transparency of the measuring data in realtime

Our product families for measuring and control technology offer a complete product range ideally adjusted to your dosing tasks.

Sensors

A large range of sensors allows exact registering of the concentration for almost every important dosing task.

We offer sensors for the following measurands:

- pH
- Redox
- Chlorine
- Conductivity (inductive and conductive)
- Chlorine dioxide
- Chlorite
- Bromine
- Ozone
- Hydrogen peroxide
- Peracetic acid
- Fluoride
- Dissolved Oxygen
- Temperature

A large range of suitable fittings grants the possibility of tailor-made and easy integration of the sensors into your process. The installation of these sensors may be effected as follows:

- In the bypass of the main stream of the process water flow
- In the dip pipe for containers or channels
- Direclty in the pipings

Correspondingly, we offer the following types of fittings:

- In-line probe housing
- Dip pipe
- Changeover fitting
- Adaptor

Measuring and Control Devices

We offer our measuring and control devices adjusted to your special dosing task in narrowly staged capacity classes.
This starts with simple transmissions of the measuring signal for forwarding it to a programmable logic controller, goes on with calibratable measuring devices with indication of the measuring value, includes controllers, that on their part are already designed for simple to complex control tasks. Integration of the control circuit into a Bus system can be effected by our PROFIBUS®-DP and CANopen-Bus components.

Control devices

- 1 channel: D1C
- 2 channels: D2C
- Multi-channel: Dulcomarin II

Measurement transducers

- Operatable, with display: DMT
- pH-transducer: PH V1
- T-transducer: Pt 100 V1
- Redox transducer: RH V1

Beside single components we offer completely mounted measuring stations for some measuring values. For reliable supervision of your measuring stations, ProMinent offers a comprehensive accessory and spare part range, even for elder components for many years after commissioning.
