Instruction and Maintenance Manual Techtrol Ultrasonic Level System

for Liquid, 'TUS'- Utratrol

Pre Installation Check :

1. Unpack the box carefully and visually check & ensure that transmitter is not damaged in transit.

2. Ensure that the supplied transmitter is as per ordered.

Installation Guidelines :

Ensure the following during location and mounting of transmitter.

1. Installation must be carried out by trained personnel

2. Ensure that the ambient temperature and process temperature must be within specified limits.

1. In outdoor location, transmitter electronics should be protected from severe weather conditions and direct sunlight, by use of canopy.

2. The location should not have any strong wind/ breeze or turbulence in vessel which may disturb ultrasonic signal.

3. Distance between tank wall and transmitters center line should be at least 110mm per meter of its measuring range. (fig 3)

4. Obstructions like( ladder, agitator, jutting tank wall) should not come in the way of ultrasonic beam (fig 4)

5. In closed tank with concave cover, transmitter should be mounted 'off-centre' and 'vertical' to minimize creation of unwanted echoes.

(fig 5)

1. In case of excessive turbulence in liquid, use of still well is suggested.

2. Not suitable for application where heavy condensation could form on the transducer face.

3. Not suitable for foaming liquids.

Mounting Considerations

1. Mount away from any source of electrical noise such as a variable speed drive or other high powered electrical devices.

2. Transmitter process flange should be of PP MOC (non –metallic) and equivalent counter flange on tank. (Fig. 6) 3. When mounted on a nozzle, ensure that the transducer face protrudes at least 5mm into the tank. (Fig. 6) If this is not

possible, ensure nozzle dimensions are as indicated in (Fig. 7)

4. The mounting nozzle should be welded in- plumb to the tank and be free from internal weld beads or other projections.

5. Ensure maximum liquid level does not come with in blanking distance (dead zone) of x'mitter..

6. Fixing of bracket to the tank should be at right angle, to ensure mounting of transmitter is vertical. (Fig. 8 & 9) 7. Mount transmitter perpendicular to liquid surface to ensure good echo from liquid surface.

Termination and Wiring :

1. During wiring of transmitter, supply should be kept off.

2. Open the enclosure cover and wire transmitter to power supply (16 to 30VDC) with correct polarity by using 2 core screen cable and its output 4-20 mA can be used further to interface with PLC or SCADA. (fig 10)

3. Wire transmitter along with Techtrol Indicators and Controller (TUIC/TLIC) as shown in fig 11.

4. Wire transmitter along with Techtrol Loop Powered Indicator as shown in fig 12.

5. Max. cable run from Ultratrol to control room should be less than 100mtrs.

Precautions :

1. Before switching on supply, ensure correct polarity of wiring.

2. Ensure transmitter enclosure is closed properly with its cover & gasket.

3. After wiring, ensure cable is routed downward before cable gland to prevent seepage of water in the enclosure. (fig 13) 4. Ensure cable should be full tight in gland ensuring zero gap between 'cable gland ID' and 'cable OD'.

Programming :

Transmitter is programmed through keys, in conjunction with display. Correct programming is essential for obtaining accuracy, reliable performance and measurement.
