Introduction:
Tuning Fork Level Switch is ideal for level control of powders and fine grained solids, especially those with a low bulk density. The ULYC incorporates a piezoelectric crystal that vibrates the fork at its natural frequency. When the fork comes in contact with material, the vibration is dampened and the switch changes state. As the fork becomes free of material, the switch changes back to its normal state. Featured in the ULYC is user-selectable fail-safe operation of the contacts. Unit is not affected by vibration from conveying systems, motors, or the movement of material. It can be mounted in any position and is available with factory built extensions for mounting on the top of the storage vessel.
Series ULYC is easy to use, with no calibration required and with no mechanical moving parts there is no routine maintenance required. The ULYC is unaffected by the dielectric constant of the sensed material, making it superior to a capacitance level switch for applications where the dielectric constant is too low, where there is more than one material being used in one vessel, and when material moisture content can change. The level switch is also good for applications when the bulk density is too low for a rotating paddle level switch. It can also detect granular material submerged in liquids of low viscosity, for example sand, gravel, or polyester chips in water.

Advantage:
Less influence caused by the tested material density and electrical parameter,Also stir,turbulence,foam,General vibration, medium viscosity, high temperature and high pressure conditions, such as smaller influence on detection also has less influence on the measurement.
Cause less influence on the measurement,so tuning fork level meter doesn’t need adjustment after times measurement.
Maintenance free:Because of tuning fork test is accomplished by electronic circuits, no moving parts, so once the installation of commissioning will not need maintenance.
Application:
tap water,mineral water,pulp, glue, dye
Mud, alkali solution and acid solution.
Beer,beverage,liquid Can produce gas liquid.
