Product Introduction
PF admittance level meter is a general type continuous level meter which is developed from capacitance level meter measurement. It consists of an electronic unit , an explosion-proof shell and hard or flexible sensor elements. The sensors have various materials and structures. Specific measurement principle and structure make it widely used in many medium measurement under complex conditions.
Product Feature
● Wide versatility: measure liquid, material level; meet requirements of different temperature, pressure and medium; be applied to severe conditions, such as corrosion and impact.
● Antihanging material: unique circuit design and sensor structure make measurement not be affected by sensor’s hanging materials. Do not need regular cleaning. It can avoid erroneous measurement.
● Maintenancefree: no moving parts in the process of measurement so no damage to mechanical parts so maintenance-free.
● Anti-interference: contact measurement, high anti-interference ability. It can overcome influence of steam, foam and stir.
●High accuracy and reliability: diversified measurement methods ensure measurement accurate and not be affected by environment. It has high stability and long life-span.
