Restrictions for use

1.3.1

Fluoride measurement WARNING Direct control of fluoride dosing is not permitted.  TISAB dosing is required to comply with certain potable water regulations. The fluoride sensor measures only the activity of free fluoride ions. This means that:  the sample pH must be higher than 5.5, otherwise the fluoride ion is present in its acid form HF and not measurable.  no complexing metals like aluminium and iron must be present, they would hide fluoride ions. The fluoride sensor measures other anions, mainly hydroxyl ions. This means that:  the sample pH must be lower than 8.0, otherwise OH- ions will interfere with the fluoride measurement. If these conditions can not be maintained, a buffer solution containing a complexing agent must be added to the sample, usually the so called TISAB buffer is used.

Product Description

2.1.

Description of the System

Application Range

The AMI ISE Universal is a Monitor for continuous measurement of either Ammonium, Nitrate or Fluoride in potable water with a Ion Selective Electrode (ISE). The ISE electrodes are called sensor in the following. The AMI ISE Universal can be operated with one of the following sensors:  Swansensor Ammonium and a reference sensor  Swansensor Nitrate and a reference sensor  Swansensor Fluoride and a reference sensor A temperature sensor is needed to keep the measuring value stable if the sample temperature fluctuates. Ammonium, Nitrate or Fluoride is measured at the inlet and at the outlet of the plant. In raw water, cleaning might be necessary in very special cases. Because potable water is normally very clean water, no problems are to be expected.

Signal Outputs

Relays

Alarm Relay

Two signal outputs programmable for measured values (freely scalable, linear, bilinear, log) or as continuous control output (control parameters programmable). Current loop: 0/4–20 mA Maximal burden: 510 Ohm Third signal output available as an option.

Fluidics

10

The flow cell M-Flow 10-3PG consists of the flow cell block [D] and the calibration vessel [F]. The sensor [A], the temperature sensor [B] and the Reference sensor FL [C] are screwed into the flow cell block [D]. The sample enters at the sample inlet [I]. It flows through the deltaT flow sensor [E] (if installed) and then through the flow cell block into the calibration vessel [F], were ammonium, nitrate or fluoride is measured. The measuring value depends on the sample temperature. The measuring value of the temperature sensor [B] is used to compensate the ISE measuring value to the standard temperature of 25 °C. The sample leaves the calibration vessel via flow cell block through the sample outlet [G] and flows into the pressure free drain [H].

Install Swansensor deltaT (Option) The Swansensor deltaT is a calorimetric flow meter based on heat dissipation. Its accuracy is ± 20%. It can be used for applications in potable water, surface water treatment and effluent. The flow measurement depends on the sample temperature and the ambient temperature. Therefore it is possible to adjust the flow measurement to the sample or ambient temperature at your site, see Adjust the Swansensor deltaT, p. 29. The following description assumes that the installation of the deltaT sensor takes place after commissioning of the monitor. Install the deltaT sensor in vertical position with the sample inlet [F] and cable gland looking downwards. To ensure laminar flow, the sample inlet must not be restricted; e.g. any fitting which creates turbulences.

CAUTION Risk of damage of the relays in the AMI Transmitter due to heavy inductive load. Heavy inductive or directly controlled loads (solenoid valves, dosing pumps) may destroy the relay contacts.  To switch inductive loads > 0.1 A use an AMI relay box available as an option or suitable external power relays. Inductive load

Small inductive loads (max 0.1A) as for example the coil of a power relay can be switched directly. To avoid noise voltage in the AMI Transmitter it is mandatory to connect a snubber circuit in parallel to the load. A snubber circuit is not necessary if an AMI relaybox is used.

Calibration A periodic calibration is necessary to check whether the sensor accuracy is in a good range. The Instrument provides a one point calibration and a two point calibration. If the measuring range is not larger than factor 10, i.e. 1 to 10 ppm, only a one point calibration should be performed. Use a two point calibration only for very large measuring ranges. To perform a one point calibration, a calibration solution which is within the expected range of the sample, must be prepared.

As control output

Signal outputs can be used for driving control units. We distinguish different kinds of controls:  P-controller: The controller action is proportional to the deviation from the setpoint. The controller is characterized by the P-Band. In the steady-state, the setpoint will never be reached. The deviation is called steady-state error. Parameters: setpoint, P-Band  PI-controller: The combination of a P-controller with an I-controller will minimize the steady-state error. If the reset time is set to zero, the I-controller is switched off. Parameters: setpoint, P-Band, reset time.  PD-controller: The combination of a P-controller with a D-controller will minimize the response time to a fast change of the process value. If the derivative time is set to zero, the D-controller is switched off. Parameters: setpoint, P-Band, derivative time.  PID-controller: The combination of a P-, an I - and a D-controller allows a proper control of the process. Parameters: setpoint, P-Band, reset time, derivative time. Ziegler-Nichols method for the optimization of a PID controller: Parameters: Setpoint, P-Band, Reset time, Derivative time Y
