Ultrasonic Level Transmitter

Ultrasonic level measurement is one of the most commonly used techniques where contact with service material is prohibitive either due to environmental conditions outside or inside the vessel.

Sultan 234 series ultrasonic level transmitter can accurately neasure the level of solids or liquids upto 60 meters. This level transmitter is a non invasive acoustic wave transmitter with flexibility and is a CE approved product.

The Sultan 234 series has found extensive application in the following industries:

Waste water/water: Open channel flow, inlet screens, sumps, pump stations, water towers, dam level, chemical, etc
Mining: Crushers, surge bins, ore passes, conveyor profile, blocked chute, stockpile, stackers, reclaimers, storage silos etc.

- Power Stations: Boiler bunkers, raw coal bunkers, ash pits, fly ash silos, etc.

The Sultan 234 ultrasonic level sensor is based on the principle of using sound waves for determining the material level. There is no contact between the transducer and the service material. The sensor displays a wide range of flexibility allowing for 2 wire loop power, AC and DC supplies all within a single amplifier. The transmitter has low installation costs and is easy to calibrate. Sultan 234 has multiple head capability to reduce cost per unit.

Operating Principle

An acoustic wave transmitted form this ultrasonic level transmitter is reflected from the surface of the service material. A built-in software processes the signal enhancing the correct signal and rejecting background noise. The waves that the Sultan 234 ultrasonic level transmitter sends are high powered. These waves ensure that there is minimal loss through the outside environment where the sensor is physically located. Even if there is any loss the high powered waves make up for it thus making the Sultan system a preferred choice over the traditionally used ultrasonic level switches. The rule is simple: more the energy transfered, more is returned. The receiver circuitry is such designed that it identifies and monitors low level return signals even when noise level is high. These signals are then compensated for temperature to provide accuracy to outputs.
