Water Level Sensor

SMKBWLP-HA level transmitter is the full stainless steel construction and full-sealed submersible intelligent level transmitter with high accuracy. It uses highly reliable and stable pressure sensor, intelligent processing circuit, precise digital temperature compensation and linearity correction technics for production. The water-proof cable connects with housing sealed, with vented tube putting in, the transmitter could be used in the water or liquid in a long time. Integrated construction and standard output signal could provide easy operation and good automatic control. With 2-wire working, compact size, light weight and easy installation and operation, it is widely used for industry field instead of normal 2-wire 4~20mADC analog output transmitter.

Features

SMKBWLRD-HA Radar Level Gauge is a liquid (material) level recording instrument in the measurement. The microwave pulse is sent by the antenna, and then is reflected by the material surface , then is received by the radar systems. Then is sent to the electronic circuit, the microprocessor can identify the microwave pulse echo regenerate the material or the surface of the liquid.

The correct signal is done by intelligent software, up to millimeter accuracy, non-applicable harsh environments.

Highlights

• Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
• Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.
• Serious dust environment on the high level meter work has little effect.
• A shorter wavelength, the reflection of solid surface inclination is better.
• Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
• The measuring range is smaller, for a measurement will yield good results.
• High signal-to-noise ratio, the level fluctuation state can obtain better performance.
• High frequency, measurement of solid and low dielectric constant of the best choice.
