ULTRASONIC LEVEL

LST400

 LST400 (click here for more info)

The LST400 is an Ultrasonic Level Transmitter capable of measuring liquid level or solid applications up to 50 ft. / 15 meters or flow rates in all types of open channel flow applications. The transmitter has a single 4-20 mADC analog output with HART 7 and five (5) relay outputs. A transducer is fitted to the top of a silo or tank, facing down towards the material being measured.

The transmitter’s microprocessor simultaneously fires an electronic pulse to the transducer and starts a timer. The transducer converts this electronic pulse to an acoustic pulse, which is directed toward the surface of the material being measured. When the acoustic pulse contacts the surface of the material, energy is reflected back to the transducer, which converts this reflected energy back to an electronic pulse. This pulse is sent back to the microprocessor, which stops the timer and determines the “time of flight” of the signal. By combining the speed of sound through air and the “time of flight” of the pulse, the microprocessor accurately determines the level of the product. Powerful software removes false echoes from the signal and electronic filters remove ambient noise.

ABB Kmicro

ABB KMICRO Ultrasonic Level Transmitter and Switch (click here for more info)

The KSONIK MICRO Ultrasonic Level Transmitter and Switch is designed to measure liquid (32 ft. / 10 m) and bulk solids (10 ft. / 3 m) levels. The range can be configured by the keyboard and display. The KMICRO is mounted on top of the vessel or tank. The microprocessor in the KMICRO fires an electronic pulse that the transducer converts into an acoustic pulse. The pulse travels to the level that is being measured and is reflected back to the transducer. The transducer then converts the energy back into an electronic signal and stops the counter in the microprocessor, which then knowing the speed of sound through the air, can accurately determine the distance. The powerful software removes false echoes and the electronic filter removes ambient noise.

ABB KmicroLP

 ABB KMICRO LP Ultrasonic Level Transmitter (click here for more info)    (loop powered unit)

The KSONIK MICRO LP Ultrasonic Level Transmitter is designed to measure liquid (16 ft. / 5 m) levels. The range can be configured by the keyboard and display. The KMICRO LP is mounted on top of the vessel or tank. The microprocessor in the KMICRO LP fires an electronic pulse that the transducer converts into an acoustic pulse. The pulse travels to the level that is being measured and is reflected back to the transducer. The transducer then converts the energy back into an electronic signal and stops the counter in the microprocessor, which then knowing the speed of sound through the air, can accurately determine the distance. The powerful software removes false echoes and the electronic filter removes ambient noise.


FEATURES:

  • Up to 16 ft. / 5 m Measuring Range
  • Low Cost, Compact Level Transmitter with Integral Transducer
  • Four Digit Alpha-Numeric Display
  • Ease of Installation & Configuration
  • Auto Variable Power Control for Difficult Applications
  • Temperature Compensation
  • Password Protection
  • No Maintenance
