Level echos from the blocking distance (BD) cannot be evaluated due to the transient characteristics of the sensor. Install the Prosonic T at a height so that the blocking distance BD is not undershot, even at maximum fill level. Use a pipe nozzle if you cannot maintain the blocking distance in any other way. The interior of the nozzle must be smooth and may not contain any edges or welded joints. In particular, there should be no burr on the inside of the tank side nozzle end. Note the specified limits for nozzle diameter and length.

Do not install the sensor in the middle of the tank (3). We recommend leaving a distance between the sensor and the tank wall (1) measuring 1/3 of the tank radius. Use a protective cover (page 18), in order to protect the device from direct sun or rain (2). Avoid measurements through the filling curtain (4). Make sure that equipment (5) such as limit switches, temperature sensors, etc. are not located within the emitting angle α. In particular, symmetrical equipment (6) such as heating coils, baffles etc. can influence measurement. Align the sensor so that it is vertical to the product surface. Never install two ultrasonic measuring devices in a tank.

Note! Make use of the echo quality display (page 14) to find the best installation position.

Screw the Prosonic T at the screw-in piece using an 60 AF spanner. In order to facilitate the wiring the housing is rotatable after installation.

Basic calibration

Reset (V9H5)

1. Enter "333" into the matrix position V9H5. This sets all matrix positions back to the factory settings. Only the linearisation parameters (V2H0 ... V2H3) and the length unit (V8H2) retain their current values.

Length unit (V8H2)

2. In V8H2, select the length unit for all subsequent inputs: V8H2 0 (Default) 1

" Empty distance (V0H1) Span (V0H2)

6. After the basic calibration the Prosonic T outputs the level in the form of a current signal. The complete measuring range (0% ... 100%) is mapped to the current interval 4 ... 20 mA. The current value (mA) is displayed in matrix position V9H8.

Endress+Hauser



6.2

Linearization

After the basic calibration, the measured value is displayed in V0H0 as a percentage of the span. The value can be converted into any other unit by the linearization function. Four different modes of linearization can be selcted in V2H0.

Linearization mode "Level" (V2H0=0)

Use this mode, if you want to display the level in the length unit, which has been selected in V8H2 (m or ft).

Linearization mode "linear"(V2H0=5, Default)

Use this mode, if you want to measure: • the level in any unit other than m, ft or %. • the volume or weight, if the volume-tolevel relationship of your vessel is linear.

Linearization mode "manual" (V2H0=2)

Use this mode, if you want to measure the volume or weight, and if a sufficient number of value pairs level/volume or level/weight are known. You can enter up to 11 value pairs into the linearization table. The table must be monotonically increasing.

Linearization mode "semi-automatic" (V2H0=3)


Use this linearization mode, if you want to measure the volume or weight, while the value pairs level/volume or level weight are not yet known. The vessel is emptied in steps. At each step, the Prosonic T automatically registers the level. The associated volume or weight must be entered manually. Step

Exception: cylincrical horizontal tank

The linearization for a cylindrical horizontal tank is performed in the following way: 1. Determine the diameter D and the total volume Vtot of the tank. 2. Multiply this value by the factors given in the table below. 3. Enter these values into the instrument as described above (Linearization mode "manual").

The current output always follows the measured value V0H0. Therefore, the 4 mA value (V0H5) and the 20 mA value (V0H6) must be adapted to the new units (see chapter 6.3).

Endress+Hauser



6.3

Current output

In V8H1 you can define the mode of the current output. You have got the following options:

Continuous output (V8H1=0, Default)

•

• Measured value

100%

V0H6 F

V0H0 V0H5

0%

4 mA

Continuous output with 4 mA threshold (V8H1=1)

Binary output 4/20mA (V8H1=2) or 8/16mA (V8H1=3)

Current 20 mA

•

In the continuous mode, the output directly follows the measured value V0H0. V0H5 and V0H6 define the interval of th e measuring range which is mapped to the current interval 4 ... 20 mA. The factory settings (V0H5=0, V0H6=100) can only be used if no linearization is present. In any other case these values must be specified in the unit of the linerization. If V0H5 is larger than V0H6, then the current output is inverted. That means the current decreases if the level increases and vice versa.

In addition to the linear scaling the 4 mA threshold becomes effective in this option. It makes sure, that the current output does not fall below 4 mA even if the measured value is less than V0H5. Use this option, if your control system can not handle currents below 4 mA.

If binary output is selected, the current only assumes two possible values: • It jumps to 20mA (or 16 mA), as soon as the measured value exceeds V0H6. • It jumps to 4mA (or 8 mA), as soon as the measured value falls below V0H5.

6.4 Echo Quality (V3H2)


Additional parameters

The echo quality of the ultrasonic signal is displayed in V3H3 in steps from 1 to 10. Additionally it is indicated by the bargraph in the matrix positions V0H8 and V0H9. Use this display in order to find the best installation position. For a sound measurement, the echo quality should be at least 5.

Interference echo suppression (V3H0)

The interference echo suppression is used when the level echo is not detected because a fitting is generating a stronger interference echo. Up to three interfernece echos can be suppressed. The suppression should be activated with the tank as empty as possible.

Step 1

Matrix position V 0H8

V 0H8

Entry / Meaning Check the dis pl ay ed dis tance between sens or diaphragm and product sur face. An interference echo suppression is necessary, if the displ ayed value is too low. Enter the actual dis tance bet ween sensor diaphragm and product sur face. Confi rm by pressing . Wait approx. 40 s. The interference echo is suppressed. Check the dis pl ay ed dis tance between sens or diaphragm and product sur face. I f the displayed value is still to low, a furhter interference echo must be suppressed. Therefore, repeat Step 2.

Temperature (V3H5)

The actual temperature at the sensor is shown in V3H5. If the limit of 80 °C has been exceeded once, the highest value ever reached remains stored (drag indicator).

Lost echo delay time (V8H3)

The lost echo delay time makes sure that no alarm will be output if the echo becomes lost for a short period of time (for example due to foam). Values between 0 and 255 s can be entered. The dafault setting is 60 s. For standard applications the lost echo delay time should be not less than 30 s.

Actual level (V3H1)

Falsifications in height in V0H9 (e.g. by temperature effects) can be corrected by entering the correct height - the actual height - in V3H1. Entering the actual height then automatically corrects the empty calibration.

First Echo Factor (V3H4)

Vessels with tightly rounded roofs (dome covers) can c ause double echos giving r ise to a display showing a level which is too low. Double echos can be excluded by increasing the first echo factor to "maximum".

Output damping (V0H4)

The effect of the output damping is to attenuate the analogue output and the measurand indication on the display of the Prosonic T. When the liquid surface is not steady, a steady reading can be obtained with the aid of the output damping. Values from 0 to 255 s can be entered. The default setting is 3 s. Please note, that the Prosonic T can not resolve level changes faster than the output damping.

The measured value is processed by the Prosonic T in two steps and subsequently output to external instruments. With the simulation function the correct operation of each of these steps can be checked.

Level simulation (V9H6=1)

Use the level simulation to check the linearisation: 1. Set V9H6=1 2. In V9H7, enter a level. Use the unit, which has been selected in V8H2 (m or ft). 3. Check if V0H0 assumes the correct value. 4. Set V9H6=0 to return to the ordinary operation mode.

Volume simulation (V9H6=2)

Use the volume simulation, to check the scaling of the output value: 1. Set V9H6=2 2. In V9H7, enter a main value (level, volume or weight). 3. Check if the output current (V9H8) assumes the correct value. 4. Set V9H6=0 to return to the ordinary operation mode.

Current simulation (V9H6=3)

Use the current simulation to check correct operation of the external instruments: 1. Set V9H6=3 2. In V9H7, enter a current (in mA). 3. Now, the specified current is present at the output. Check, if the external instruments respond correctly to this current. 4. Set V9H6=0 to return to the ordinary operation mode.
