How often should i match? We currently perform monthly validations and sometimes the validation fails so i like to match. A chap here said you should only match yearly which doesnt make sense to me. Please could you clarify. I work at a water treatment works

  • Page 10: Product Description

    Product Description Product Description Application The AMI Turbiwell is used to measure turbidity in potable water, sur- face water, effluents and water steam cycles. The turbidimeter is also suitable for the measurement of other liquids of which the turbidity correlates with the concentration of a suspend- ed solid or an emulsified liquid, e.g.
  • Page 11 AMI Turbiwell Product Description Alarm Relay Two potential free contacts. Alternatively:  Open during normal operation, closed on error and loss of power.  Closed during normal operation, open on error and loss of power. Summary alarm indication for programmable alarm values and in- strument faults.

  • Page 12: Operation

    To obtain the turbidity value of the sample, the diffuse radiation is de- termined at an angle of 90°. The AMI Turbiwell uses a non-contact turbidimeter to avoid fouling of optical surfaces. The light beam of the LED (light emitting diode) impinges the water surface and is refracted.
  • Page 13 The kits are available as an option. Calibration The AMI Turbiwell is factory-calibrated, therefore it is not necessary to perform a calibration in the field. The emission intensity of the LED is monitored by an external photodiode. A loss of intensity due to ag- ing will be automatically compensated.

  • Page 47: Calibration, Matching And Verification

    The calibration is accepted if the deviation is less than 25 % of the factory calibration. The long-term stability of the AMI Turbiwell can be verified with a ver- ification kit that must be matched against the current calibration.

  • Page 48: Ppm Calculation, E.g. "Oil In Water

    The calibration line is defined by 2 points: zero point and a scale point (slope). For the determination of the zero point, a sample with- out the opacifier (x = 0) must be supplied to the AMI Turbiwell. The average value over a defined time period is automatically saved as the zero point.
  • Page 49 AMI Turbiwell Instrument Setup Considerations Considerations for a reliable measurement:  The sample must always have the same grade of homogeniza- tion to receive quantitative results. Adequate homogenization can be achieved with a centrifugal or a gear pump.  The distance and the time period from sampling to measure- ment should be short enough to ensure that the drop size does not essentially change.
  • Page 50 AMI Turbiwell Instrument Setup Process The following must be considered before starting calibration:  Drain the measuring chamber and clean it if necessary. calibration  For the calibration, oil-free process water and oil is needed. The calibration solutions are prepared in a vessel with a vol- ume of approx.10 liters.
