Page 22: Verifying The Ultrasonic Signal Waveform
2.6.4 Verifying the Ultrasonic Signal Waveform 2.6.4.1 Purpose The purpose is to verify the proper operation of the analyzer with regard to the ultrasonic echo. Its visualized waveform (time vs. amplitude plot) can be an aid to identify problems which are related to the process (gas bubbles, faulty cable etc.) When you are asked by the factory or your sales agent to submit a waveform for diagnostics purposes, please follow this procedure. - Page 23 the echo stored on the USB stick. If more than 100 echoes are stored, the first JPG- file will be overwritten. 2.6.4.3 Examples of ultrasonics waveforms Please refer to the previous section for a general explanation. This echo is extremely good, as there is no noise before the echo (left = before).

Page 28: Adjusting Polynomials
Changing polynomials may lead the incorrect concentrations. Only perform this action if Rhosonics asked you to do so. Rhosonics may send you a new Liquid Datasheet with new liquid polynomials to improve the concentration calculation. To enter the new polynomial values into a liquid follow the next steps. -
Page 29: Calibration
4. Calibration You may calibrate the analyzer in order to assure optimal analysis results. This section describes the different calibration routines, and the intervals which are required. 4.1 Types of calibration The following table lists the different types of calibration, their purpose and the interval required to perform these calibrations. -
Page 30: When Needed
The analysis result and the linearity highly depends on the integrity of the temperature circuit. The temperature offset calibration provides a simple and effective way to apply corrections to the temperature measurement, should this be necessary. 4.2.2 When needed Check the temperature reading regularly, and perform a calibration when the reading error exceeds 0.5 ºC. -
Page 31: Field (Sample) Calibration
IMPORTANT: The zero calibration must be preferably done inline, with water, WITHOUT ANY GAS BUBBLES. When done inline, at atmospheric pressure, the water may be treated by ultrasonic removal of all gas bubbles. In the Calibration menu press [US Zero] ... - Page 32 calibration will have effect ONLY on the liquid which you have made the active liquid calibration. The below procedure provides a brief guideline for the necessary steps. The analyzer must be powered up for at least 4 hours Select the product from the list (Through menu Liquids-Liquid Select). ...

Page 33: Automation And Communication
5. Automation and communication. The Rhosonics analyzer has several features to minimize operator interference. Most of them are related to remote product switching and regular calibration routines. CAUTION: Be aware that changing of any data can stop the communication. Do not change any data if you do not fully understand the effect of all actions to the performance of the analyzer. -
Page 34: External Hold Function
5.4 External Hold function 5.4.1 Purpose External HOLD is useful during product stand still. Due to the heating of the pipe, the temperature of the liquid may not be stable. The External Hold function will stop the measurement and freeze all outputs. 5.5 Automatic calibration 5.5.1 Auto dead time calibration The purpose of this feature is to reduce small errors, both operator and system errors. -
Page 35: Maintenance
6. Maintenance 6.1.1 Introduction Most maintenance is covered by the Chapter “Calibration” of this manual. The table in this chapter gives an overview of the most common maintenance requirements of the system. 6.1.2 Probe maintenance The operation of the probe can be checked by following the procedure as described in the Calibration Chapter of this manual. -

6.1.4 4-20 mA OUTPUT calibration It is normally NOT necessary to (re)calibrate the analog ouputs. If there is a doubt about the analog conversion of the concentration value, or in case you wish to do a system loop calibration, this procedure may be followed. Note that the sole purpose of this calibration is to calibrate the electronic output, which is normally drift free. -
Page 37: Frequently Asked Questions
7. Frequently asked questions 7.1.1 Installation questions Q: Do I need to calibrate the analyzer prior to installation? A: The analyzer has been calibrated and tested in the factory. There is no need to (re)calibrate the analyzer before installation, because all specific adjustments and calibrations can be done with a fully installed analyzer. - Page 38 Q: During certain process conditions, it can happen that gas bubbles are present in the liquid. How does this affect the measurement? A: The Rhosonics Ultrasonic Analyzer automatically detects the presence of product and gas bubbles. It will then freeze the measurement until a next valid measurement is possible. Due to its unique method of operation, the analyzer continues to operate reliably during upset process conditions.
