Tek-Trol Tek-Sound 4200B Ultrasonic Level Transmitter | Non-Contact Sensor

TEK-TROL TEK-SOUND 4200A ULTRASONIC LEVEL TRANSMITTER | NON CONTACT SENSOR

The Tek-Sound 4200A utilizes advanced ultrasonic technology to measure levels without coming into contact with the media. It emits high-frequency sound pulses that reflect off the material surface; the time-of-flight is then converted into a precise electrical signal. Featuring “Fast-On” technology and advanced false-echo suppression, it ensures reliable readings even in vessels with internal obstructions or turbulence. Its compact design and user-friendly interface make it ideal for demanding environments where traditional contact sensors are prone to failure.

PRODUCT USES:

  • Water & Wastewater: Monitoring levels in open channels, sumps, wet wells, and storage tanks.
  • Chemical Processing: Tracking corrosive liquids in plastic or metal tanks where non-contact is required for sensor longevity.
  • Food & Beverage: Sanitary level monitoring for juices, milk, or ingredients.
  • Solids Monitoring: Level measurement for powders, grains, and small granules in hoppers or silos.

 

TEK-TROL TEK-SOUND 4200A ULTRASONIC LEVEL TRANSMITTER | NON CONTACT SENSOR

Tek-Sound 4200A Ultrasonic Level Transmitter are commonly used level measurement instruments used in several industries for the continuous measurement of the level and volume of different media in open and closed tanks and for flow measurement in open channels. They are a cost-effective, reliable, and accurate solution in a wide array of applications involving both solids and liquids. Since they are non-contact devices, they require minimal maintenance and suffer minimal wear and tear. Additionally, this also ensures that they can be used under difficult process conditions.

PRODUCT USES:

  • Water & Wastewater: Monitoring levels in open channels, sumps, wet wells, and storage tanks.
  • Chemical Processing: Tracking corrosive liquids in plastic or metal tanks where non-contact is required for sensor longevity.
  • Food & Beverage: Sanitary level monitoring for juices, milk, or ingredients.
  • Solids Monitoring: Level measurement for powders, grains, and small granules in hoppers or silos.
