|2"|0.35 m (1.1 ft)|8 m (26 ft)|3.5 m (11 ft)|



## **Time-of-flight method** 

The sensor of the instrument transmits ultrasonic pulses in the direction of the product surface. There, they are reflected back and received by the sensor. The instrument measures the time t between pulse transmission and reception. The instrument uses the time t (and the velocity of sound c) to calculate the distance D between the sensor membrane and the product surface: 

D = c  t/2 

As the device knows the empty distance E from a user entry, it can calculate the level as follows: 

L = E - D 

An integrated temperature sensor (NTC) compensates for changes in the velocity of sound caused by temperature changes. 

## **Interference echo suppression** 

The interference echo suppression feature on the instrument ensures that interference echos (e.g. from edges, welded joints and installations) are not interpreted as a level echo. 

## **Calibration** 

Enter the empty distance E and the span F to calibrate the device. 

## **Blocking distance** 

Span F may not extend into the blocking distance BD. Level echos within the blocking distance cannot be evaluated due to the transient characteristics of the sensor.

## **Input** 

**Measured variable** The distance D between the sensor membrane and the product surface is measured, see also figure  ä 3. Using the linearization function, the device uses D to calculate: • Level L in any units • Volume V in any units • Flow Q across measuring weirs or open channels in any units **Measuring range** The measuring range is limited by the range of a sensor. The sensor range is, in turn, dependent on the operating conditions. To estimate the actual range, proceed as follows (see also the calculation example in the diagram): 

1. Determine which of the influences shown in the following table are appropriate for your process. 

2. Add the corresponding attenuation values. 

3. From the total attenuation, use the diagram to calculate the range. 

|**Fluid surface**|**Attenuation**|
|---|---|
|Calm|0 dB|
|Waves|5 to 10 dB|
|Strong turbulence (e.g. stirrers)|10 to 20 dB|
|Foaming|Please contact your Endress+Hauser sales representative.|
|||
|**Bulk material surface**|**Attenuation**|
|Hard, rough (e.g. rubble)|40 dB|
|Soft (e.g. peat, dust-covered clinker)|40 to 60 dB|



|**Dust**|**Attenuation**|
|---|---|
|No dust formation|0 dB|
|Little dust formation|5 dB|
|Heavy dust formation|5 to 20 dB|
|||
|**Filling curtain in detection range**|**Attenuation**|
|None|0 dB|
|Small quantities|5 to 10 dB|
|Large quantities|10 to 40 dB|
|||
|**Temperature difference between**<br>**sensor and product surface**|**Attenuation**|
|to 20 °C (68 °F)|0 dB|
|to 40 °C (104 °F)|5 to 10 dB|
|to 60 °C (140 °F)|10 to 15 dB|

- Strong turbulence surface approx. 50 dB 

- • No dust formation 0 dB • Filling curtain in detection range 10 dB 

- • Temperature diff. < 20 °C (68 °F) 0 dB approx. 50 dB  range approx. 3.5 m (11 ft) for FMU30 2" sensor 

These measuring conditions have been taken into account during the calculation of the maximum measuring range in solid applications.

## **Output** 

||**Output signal**|4 to 20 mA|
|---|---|---|
|**Signal on alarm**||Error information can be accessed via the following interfaces:|
|||• On-site display (error symbol, error code and plain text description)|
|||• Current output, signal on error can be selected (e.g. according to NAMUR recommendation NE43)|
|**Output damping**||Freely selectable, 0 to 255 s|
|**Linearization**||The linearization function of the instrument allows conversion of the measured value into any unit of length|
|||or volume. In open channels or measuring weirs, also a flow linearization is possible (calculation of the flow|
|||from the measured level).|



The linearization table for calculating the volume in an horizontal cylindrical tank is preprogrammed. You can also enter any number of other tables containing up to 32 value pairs either manually or semi-automatically (by filling the vessel under controlled conditions).

|||* whichever is greater|
|**Influence of the vapor**||The vapor pressure at 20 °C (68 °F) gives a hint on the accuracy of the ultrasonic level measurement. If the|
|**pressure**||vapor pressure at 20 °C (68 °F) is below 50 mbar (1 psi), ultrasonic level measurement is possible with a very|
|||high accuracy. This is valid for water, aqueous solutions, water-solid-solutions, dilute acids (hydrochloric acid,|
|||sulfuric acid, ...), dilute bases (caustic soda, ...), oils, greases, slurries, pastes, ...|
|||High vapor pressures or outgassing media (ethanol, acetone, ammonia, ...) can influence the accuracy. If|
|||conditions like these are present, please contact your Endress+Hauser sales representative.|

- Protect the device against direct sun or rain (2)  ä 26 "Weather protection cover". 

- Avoid measurements through the filling curtain (4). 

- For solid application where bulk solid cones appear, align the sensor membrane perpendicular to the surface. 

- Make sure that equipment (5) such as limit switches, temperature sensors, etc. are not located within the emitting angle  . In particular, symmetrical equipment (6) such as heating coils, baffles etc. can influence measurement. 

- Never install two ultrasonic measuring devices in a tank, as the two signals may affect each other. 

• To estimate the detection range, use the 3 dB emitting angle  .

## **Blocking distance, nozzle installation** 

Install the instrument 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. To minimise disturbing factors, we recommend an angled socket edge (ideally 45°).

## Caution! 

If the blocking distance is undershot, it may cause device malfunction. 

## Note! 

In order to notice if the level approaches the blocking distance, you can specify a safety distance (SD). If the level is within this safety distance, the instrument outputs a warning or alarm message.
