Ultrasonic Level Sensor

LUC-M**

Compact transmitters for non-contact

level measurement of fluids, pastes and

coarse bulk materials

Application

• Continuous, non-contact level

measurement in fluids, pastes,

sullages and coarse bulk materials

• Flow measurement in open channels

and measuring weirs

• System integration via:

- HART (standard), 4 mA ... 20mA

- PROFIBUS PA

• Maximum measuring range:

LUC-M10:

- 5 m (16.4 ft) in fluids

- 2 m (6.6 ft) in bulk materials

LUC-M20:

- 8 m (26.2 ft) in fluids

- 3,5 m (11.5 ft) in bulk materials

LUC-M30:

- 15 m (49.2 ft) in fluids

- 7 m (23 ft) in bulk materials

LUC-M40:

- 10 m (32.8 ft) in fluids

- 5 m (16.4 ft) in bulk materials

Features

• Quick and simple commissioning via

menu-guided on-site operation with

four-line plain text display

• Envelope curves on the on-site display

for simple diagnosis

• Suitable for explosion hazardous

areas (Gas-Ex, Dust-Ex)

• Linearisation function (up to 32 points)

for conversion of the measured value

into any unit of length, volume or flow

rate

• Non-contact measurement method

minimizes service requirements

• Optional remote display and operation

(up to 20 m from transmitter)

• Installation possible from thread G1½

or 1½ NPT upwards

• Integrated temperature sensor for

automatic correction of the

temperature dependent sound

velocity

Ultrasonic Level Sensor LUC-M** Input Input Measured variable The distance D between the sensor membrane and the product surface is measured. Using the linearisation 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.

Ultrasonic Level Sensor LUC-M** Output Example (for LUC-M30) For typical solid applications, a certain amount of dust coverage is normally present. Therefore, the following range results from the table and the diagram. • Dust-covered rubble approx. 50 dB • No dust development 0 dB • No filling curtain in 0 dB detection range • Temperature difference < 20 K 0 dB approx. 50 dB  range approx.

Ultrasonic Level Sensor LUC-M** Installation conditions Installation conditions for level measurements 2 3 4 7 1 5 1/6D D 6 L α r • 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 1/6 of the tank diameter. • Use a protective cover, in order to protect the device from direct sun or rain (2). • Avoid measurements through the filling curtain (4).
PAGE 13
Ultrasonic Level Sensor LUC-M** Installation conditions Installation conditions for flow measurements • Install the LUC-M** at the inflow side, as close above the maximum water level Hmax as possible (take into account the blocking distance BD). • Position the LUC-M** in the middle of the channel or weir. • Align the sensor membrane parallel to the water surface. • Keep to the installation distance of the channel or weir.
PAGE 14
Ultrasonic Level Sensor LUC-M** Installation conditions Install the LUC-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 should be no burr on the inside of the tank side nozzle end. Note the specified limits for nozzle diameter and length.
