Fluoride Measurement

The Fluoride Sensor is a potentiometric sensor working with ion selective electrodes (ISE) and a reference electrode supplying the measurement signal (mV).

Basic Principles for the Measurement of Fluoride in Aqueous Solutions

Potentiometric determination of the Fluoride concentration is effected analogically to pH measurement. Instead of a glass diaphragm, a LaF3 single crystal is used. Thus, selective penetration of Fluoride Ions in the interior of the electrode is enabled. Here, the concentration-dependent potential is measured against the reference electrode as voltage and analyzed analogically to the pH measurement.

Application Areas

Typical application areas of the Fluoride Sensors are Water treament generators, where Fluoride is dosed into the drinking water for the prevention of cavities and continuous measurement is applied as means of monitoring.

Our Program offers the following Advantages:

For easy and fast installation, Fluoride sensors are only offered as ready for operation and mounted on PE-panels, i.e. plug & play with optimally inter-adjusted components.
Exact and reliable real-time measurement
Long-term stable measurement
No additional conditioning reagents (e.g. TISAB) necessary
Easy calibration by means of ProMinent's complete Photometer-Kit (Type DT2)

The Fluoride Electrode is an ion-selective Sensor based on the potentiometric measuring principle, determines and monitors the concentration of the anion Fluoride in the fluoridation of drinking water. The corresponding frame conditions must be observed.

Advantages

Efficient process monitoring through precise potentiometric real-time measurement (short response times)
No cross sensitivities or interference due to the use of a selective LaF3-crystal
Minimal temperature influence due to extraordinarily fast external temperature compensation
Potentiometric principle minimizes disturbances due to flow changes.
Operating pH range 5.5 to 8.5
No additional conditioning chemicals (e.g. TISAB) necessary.
Ease of commissioning due to potentiometric measuring principle
Long sensor; life due to patent-pending inner electrodes.
Easy calibration by means of a complete photometer kit (type DT2) is available
Short delivery times allows for rapid replacement
Private labeling and price allowance for OEM partners

When discharging to atmosphere, what steps will improve repeatability of dosing?

Installing a spring in the discharge valve of the pump gives some improvement, but for the maximum improvement, a backpressure valve should be installed at the end of the line.

What variables can be measured or controlled with ProMinent equipment?

We can measure or control pH, Redox, Free or Total Chlorine, Chlorine Dioxide, Conductivity, Ozone, Peracetic Acid, Hydrogen Peroxide and Dissolved Oxygen.

Can you explain what the different options are using the Ident-code for the D1C controller?

The Identcode for a D1C has 13 parameters that can be specified. The first parameter is the type of mounting such as wall or panel mount. Then the operating Voltage must be selected. The measured variable is the parameter being measured such as pH, chlorine, Redox ? The next selection is the connection of measured variable, which selects how the sensor is wired, such as an SN6 connector. The correction variable selects whether there is pH or temperature correction. The next variable is feed forward capability. This signal can be used for metering proportional to the flow rate. The control input allows control by contact closure. The signal output function can be set up as measured, controlled or correction variable. The power control variable pertains to the alarm functions and how and what they control. The pump control option is set up for whether pumps will be controlled. The control characteristic sets the pump up for proportional control band or the more sophisticated PID control. The interface is not used at this time. The last variable allows for the selection of the language.

What is feed forward control?

This signal can be used for metering proportional to the flow rate.
