Page 14: Error Communication Through Analog Outputs
CAUTION: Scaling the output to a high range, i.e. 0~100 wt%, results in loss of accuracy. The accuracy of the output is 0,05 % of scale. Choosing a smaller range (difference between low and high value) results in a better resolution. In the above example, the accuracy of the output is 0,1% of (15-10), which equals 0,0025 wt%. -

“bulk” value of the liquid. When fast response is not required, we strongly recommend setting the τ63 time between 5 and 20 seconds. Since smoothing affects the response time, the best setting is a trade-off between accuracy and response time. A decay rate of 5 seconds is recommended for most applications. -
Page 16: Display Smoothing
► Press [2Digits] or [3 Digits] on the Resolution page (automatic return to the Display configuration page) 3.3.3 Display smoothing This setting is the same as the decay time for the analog outputs. The result is that concentration values are smoothened before they are sent to the output. A decay rate of 5 seconds is recommended for most applications. -

In addition, you may select whether the alarms are activated during fault conditions (Normal) or activated when no alarm is present (inverted operation). 3.5.2 Preparation. • Determine which value you wish to monitor with each alarm. • Determine whether you wish the alarm relay contacts to be activated during normal operation (no alarm) or during a fault condition. -

Page 21: Verifying The Ultrasonic Signal Waveform
3.6.4 Verifying the Ultrasonic Signal Waveform 3.6.4.1 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 22 3.6.4.3 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). The system will measure the time based on the first negative going ½-period, which is clearly identifiable.

Page 23: Factory Diagnostics To Usb
For trouble shooting purposes, the factory or the service engineer of your sales representative may ask you to copy the factory settings to a USB stick and send these settings to Rhosonics. 3.6.5.2 Preparation. NOTE: Please read the previous section(s) to obtain information about the type of memory stick to be used. - Page 24 Each time, a unique image is stored in the \RHO\HDCOPY of the USB stick. By copying relevant pages, either during calibration or during operation, it will be easy to communicate specific pages of interest to the USB stick. Once you are done with copying display images to the USB stick, you may take out the stick and view the images on your PC, e-mail them to your service agent, etc.

Page 25: Liquid Selection And Editing
4. Liquid Selection and Editing 4.1 Liquid (product) selection 4.1.1 Purpose: To make one previously stored liquid calibration the new and active calibration. When your analyzer is used for one specific type of liquid only, the liquid select procedure may not be of interest to you. -
Page 26: Purpose
To restore field calibration data or duplicate field calibration data from other analyzers into this analyzer. • To edit polynomial constants according to Liquid Datasheet sent by Rhosonics 4.2.3 Preparation for editing liquid parameters • Obtain the liquid data sheet from the factory •... - Page 27 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 28: Calibration
5. 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. 5.1 Types of calibration The following table lists the different types of calibration, their purpose and the interval required to perform these calibrations. -
Page 29: Background And Functions Of Zero And Clear Liquid Calibration
5.2 Background and Functions of Zero and Clear Liquid Calibration. The Rhosonics Model 9670 analyzer works with special US sensors, which measure the following parameters by ultrasonic means: • Temperature • Internal transducer efficiency • External transducer efficiency (acoustic impedance) •... -
Page 30: Temperature Offset
Figure 27: CALIBRATION page 5.4 Temperature offset 5.4.1 Purpose To calibrate the ultrasonic temperature measurement. Only its offset is corrected, its span needs no calibration. 5.4.2 When needed It is necessary when you first connect the sensors to the analyzer. Also, when you swap the sensor on channel 1, it is necessary to recalibrate the temperature. -
Page 31: When Needed
The main purpose is to improve the accuracy of the TDS measurement. For this calibration we recommend using water with less than 0,2 x the accuracy you require. This calibration applies an adjustment factor to the sound path, as the sound speed of water is known to the analyzer at each temperature. -
Page 32: High Density Or Field Calibration
for water), as well as the amount of solids. These calibration constants are called certified temperature and certified TSS solids. The procedure can be done in water, when there is no way to calibrate under real process conditions. When you have done the calibration in water, SG reading, as well as the temperature need no further calibration. -
Page 33: Field (Sample) Calibration
► Press the Start button. The next menu indicates a counter that counts back from 60 seconds. Wait until it reads -1. The density will now be corrected within +/- 0.1 °C and the SG within +/- 0.1%. ► The correct factors are determined when the counter stops. Press OK (V). The density reading should be stable within +/- 1 g/l. -
Page 34: Automation And Communication
6. 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 35: External Hold Function
6.4 External Hold function 6.4.1 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. 6.5 Automatic calibration 6.5.1 Auto dead time calibration The purpose of this feature is to reduce small errors, both operator and system errors. -

Of the above measurements, the sound speed and the temperature may not be available. In fact, the Rhosonics Model 9620 analyzer does not use the sound velocity for analysis. The sound speed is depending on the DISSOLVED solids only, and NOT depending on the amount of total solids. -

Page 39: Frequently Asked Questions
8. Frequently asked questions 8.1.1 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 40 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.
