The working principle of a tuning fork level gauge uses a sensing element in the shape of a tuning fork, which has two sharp teeth inserted into the chamber or tank where the target medium will be present. The tuning fork sensing element vibrates at its natural resonance frequency by establishing motion within the sensing element or tuning fork. In the most common implementation of the working principle of a vibrating fork level switch, the harmonic vibration of the tuning fork sensing element is established using piezoelectric technology< Br/>

Setting guide:

1) Insert the fork into the medium to be tested at a depth of approximately 10mm, and press&quo; SET” Press the button until the red and greedy LEDs flash alternately at least 2 times, then release the button; SET” Press the key, at which point the red LED flashes, then press&quo; SET” The button, red and greedy LEDS flash alternately, and then both light up< Br/>
2) Remove the fork from the medium, the green LED lights up, and the red LED goes off (NC closes through COM, NO and COM open). Now insert the fork into the medium again, and both LEDs light up (NO closes through COM, NC and COM open). Now the setup is complete< Br/>


Attention:

The default density of water is set to 1g/cm3, if the target medium density≥ 1g/cm3 does not require self inspection. When the target medium density< At 1g/cm3, a self check is required< Br/>
The default sensitivity is the highest. For materials with irregular surfaces and fluctuations, please set a lower sensitivity< Br/>
Avoid installing in locations with severe vibrations< Br/>
