DRFT-99 RF admittance level meter
I Product Introduction
RF admittance level meter is a general type continuous level meter which is developed from the capacitance level meter technology. The meter consists of a electronic unit, a explosion-proof shell and hard or flexible probe elements. The sensors have a variety of materials and structures. It is widely applied in the level measurement of many medium under complex condition on the basis of specific measurement principle and structure.
Typical Application:
Conductive, insulating liquid - --chemical, oil field, water and sewage treatment
Conductive and insulating paste---papermaking, pharmaceutical, water and wastewater treatment
Powder: gray, powder --- power plants, metallurgy, cement
Particle: coal, cereal --- power plants, metallurgy, food
Interface: stratified two liquids (oil-water interface) ---Oilfield, chemical.
Feature
1.Versatility: It can measure liquid level as well as material level. It can meet the requirements of different temperature, pressure and medium. It can be applied to harsh conditions, such as corrosion and impact.
2.Anti-hanging material: The unique circuit design and sensor structure make the measurement not be affected by the sensor hanging materials. It doesn't need regular clean. It can avoid erroneous measurement.
3.Maintenance-free: There is no moved parts in the process of measurement, so there is no damage to the mechanical parts. Therefore, it needs no maintenance.
4.Anti-interference: It adopts contact measurement and has high anti-interference ability, which can overcome the influence of steam, foam and stir.
5.Accuracy and Reliability: Diversified measurement methods makes the measurement accurate and not be affected by the environment. It has high stability and long life-span.
