Ultrasonic Level Measurement

prosonic M FMU 40/41/43

Compact transmitters for non-contact level measurement of fluids, pastes and coarse bulk materials

FMU 41

FMU 40

Application

The compact Prosonic M transmitters are used for continuous, non-contact level measurement in fluids and coarse bulk materials.

Additionally, the sensors can be used for flow measurement in open channels and measuring weirs.

The following interfaces are available for system integration:

• HART

• PROFIBUS-PA

• Foundation Fieldbus The maximum measuring range for

Prosonic M sensors are:

• FMU 40:

• FMU 41:

• FMU 43:

(standard), 4 to 20 mA

– Fluids, 16 feet (5 m) – Bulk solids, 6 feet (2 m)

– Fluids, 26 feet (8 m) – Bulk solids, 12 feet (3.5 m)

– Fluids, 50 feet (15 m) – Bulk solids, 23 feet (7 m)

FMU 43

Features and benefits

• Simple, menu-guided on-site operation with four-line plain text display

• Envelope curves on the on-site display for simple diagnosis

• Easy operation, diagnosis and measuring point documentation with the supplied ToF Tool operating program

• Alignable NEMA 6P (IP 68) aluminum housing

• Optional remote display and operation

• Installation via 1-1/2” NPT, 2” NPT or 4” universal slip-on flange

• Integrated temperature sensor for Time-of-Flight correction provides accurate measurements, even with temperature changes

• Linearization function (up to 32 points) for measured value output in any unit of length, volume, or flow rate

• Non-contact measurement method, therefore almost independent of product properties

Time-of-Flight method

The Prosonic M sensor transmits ultrasonic pulses in the direction of the product surface. The ultrasonic pulse is reflected back and received by the sensor. The Prosonic M electronics measures the time t between pulse transmission and reception. Using the time t (and the velocity of sound c), the system calculates the distance D between the sensor membrane and the product surface

D = c x t/2

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

L = E - D

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

Interference echo suppression

The interference echo suppression feature ensures that interference echos (such as welded joints, internal ladder steps, edges and installations) are not interpreted as a level echo.

Equipment architecture

Calibration

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

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.

The distance D between the sensor membrane and the product surface is measured (page 2). 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 The measuring range is limited by the range of a sensor. The sensor range is, in turn,

dependent on operating conditions. The diagram below defines the effect that echo attenuation has on the sensor’s measuring range. The ideal echo attenuation curves for each sensor are shown in the diagram. A number of echo attenuation sources that affect proper sensor selection are shown in the table.

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

2. Add the corresponding attenuation values.

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

Linearization tables for calculating volume in horizontal cylindrical tanks are 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).

Install the Prosonic M at a height so that the blocking distance BD is not interferred with, even at the maximum fill level. Usa a pipe nozzle if you cannot maintain the sensor blocking distance in any other way. The interior of the nozzle must be smooth and cannot contain any edges or welded joints. In particular, remove any burr on the inside of the tank side nozzle end. Note the specified limits for nozzle diameter to length. Nozzles which extend into the vessel should be cut at an angle of 45° to minimize echo disturbances.

Caution ! The sensor may malfunction if the blocking distance is not above the maximum level.

NOTE: In order to prevent the level from entering the blocking distance, a safety distance (SD) can be specified. If the level is within the safety distance, the Prosonic outputs a warning or alarm message.
