Time-of-flight method

The sensor of the Prosonic M transmits ultrasonic pulses in the direction of the product surface. There, they are reflected back and received by the sensor. The Prosonic M 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 Prosonic M 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.

System integration via Fieldgate

Vendor Managed Inventory

By using Fieldgates to interrogate tank or silo levels remotely, suppliers of raw materials can provide their regular customers with information about the current supplies at any time and, for example, account for them in their own production planning. For their part, the Fieldgates monitor the configured level limits and, if required, automatically activate the next supply. The spectrum of options here ranges from a simple purchasing requisition via e-mail through to fully automatic order administration by coupling XML data into the planning systems on both sides.

Remote maintenance of measuring equipment

Fieldgates not only transfer the current measured values, they also alert the responsible standby personnel, if required, via e-mail or SMS. In the event of an alarm or also when performing routine checks, service technicians can diagnose and configure connected HART devices remotely. All that is required for this is the corresponding HART operating software (e.g. FieldCare) for the connected device. Fieldgate passes on the information transparently, so that all options for the respective operating software are available remotely. Some on-site service operations can be avoided by using remote diagnosis and remote configuration and all others can at least be better planned and prepared.

The complete measuring system consists of devices and:

1 Fieldgate FXA520 2 Multidrop Connector FXN520

Note! The number of instruments which can be connected in mutidrop mode can be calculated by the "FieldNetCalc" program. A description of this program can be found in Technical Information TI00400F/00/EN (Multidrop Conncector FXN520). The program is available form your Endress+Hauser sales organisation or in the internet at: "www.endress.com  select your country download search: Fieldnetcalc

Input

Measured variable The distance D between the sensor membrane and the product surface is measured.

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)

Dust Attenuation

No dust formation 0 dB

Little dust formation 5 dB

Heavy dust formation 5 to 20 dB

Example (for FMU43)

For typical solid applications, a certain amount of dust coverage is normally present. Therefore, the following range results from the table and the diagram:

Operating frequency

• Dust-covered rubble approx. 50 dB

• No dust formation 0 dB

• No filling curtain in detection range 0 dB

• Temperature diff. < 20°C 0 dB

approx. 50 dB  range approx. 7 m (23 ft)

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

Sensor Operating frequency

FMU40 approx. 70 kHz

FMU41 approx. 50 kHz

FMU42 approx. 42 kHz

FMU43 approx. 35 kHz

Linearization The linearization function of the Prosonic M 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). The supplied FieldCare operating program can automatically calculate the table for any tank, weir or flume and upload it into the device. Flow curves for open channels can be calculated and entered into the instrument by the FieldCare as well ( ä 29, "Operation with FieldCare").

Influence of the vapor pressure

Installation variants FMU40, FMU41

The vapor pressure at 20 °C (68 °F) gives a hint on the accuracy of the ultrasonic level measurement. If the 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.

• 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 . 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 (7).

• 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 Prosonic M 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 sh ould be no burr on t he in side 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°).
