Different liquid level measuring instruments should be used to measure different materials and working conditions. The main liquid level measuring instruments at home and abroad include: anti-rotation liquid level switch, tuning fork liquid level switch, radio frequency admittance liquid level switch, radar liquid level meter, vibrating rod liquid level switch, etc.

Since the principles and performance of liquid level measuring instruments are different, it is very important to choose the best measuring instrument in actual production.

(1) Anti-rotation liquid level switch

Since the anti-rotation material level switch has lubricated moving parts, it does not meet the food level requirements of flour mills.

(2) Tuning fork level switch

Ordinary tuning fork level switches made in China are prone to perforation when measuring powdery materials, resulting in false alarms. Therefore, ordinary tuning fork level switches made in China are not suitable for flour mills.

(3)RF admittance level switch

Due to structural design reasons, the RF admittance level switch cannot meet dust explosion-proof requirements.

(4)Single rod liquid level switch

It is often used in food processing, but due to its single-rod structure, it has poor anti-hanging ability, is prone to false alarms, is not cheap, and is not cost-effective.

(5)Double-rod liquid level switch

Work is more stable and reliable. At the same time, the circuit and structural design can meet the requirements of dust explosion protection and are very suitable for material measurement in flour mills.
