Intelligent RF admittance level meter
2011-6-7 9:01:09

Jinhu Dongxiang Instrument Co., Ltd. officially produced and sold intelligent RF admittance level meter in 2011. Level-Ease20000 intelligent RF admittance level meter is a new generation of intelligent continuous level (liquid level) Bit) measuring instrument, the product adopts the core module of "Level-Ease Radio Frequency Detection Technology" of ARJAY Engineering Company, which has the same performance and quality as the original product of ARJAY Engineering Company.

Level-Ease20000 intelligent RF admittance level meter adopts "Level-Ease RF detection technology" and modern microcomputer processing technology, which solves the problems of large temperature drift, difficult calibration and fear of adhesion of traditional level meters, and is widely applicable to various industries Continuous measurement of liquid, granule and bulk material silo levels. The special impact and abrasion resistant probe sheath material used in this product is the first of its kind at home and abroad, and is especially suitable for measurement in high temperature, high pressure, strong corrosion, strong adhesion, strong impact, strong wear, and large dust environments. There are other types of level meter that are incomparable. zzyfwh.com

working principle

Level-Ease20000 intelligent RF admittance level meter consists of sensors and control instruments, as shown in the figure. The sensor can be mounted on the roof of the warehouse using rod, coaxial or cable probes.

The pulse card in the sensor can convert the level change into a pulse signal and send it to the control instrument. After the control instrument is processed and converted into an engineering quantity display, the continuous measurement of the level is realized. Thanks to the "Level-Ease RF admittance detection technology", it improves reliability and makes installation and commissioning very easy.

Features

Simple calibration: Any two-point warehouse height can be used for automatic calibration at one time.

Strong adaptability: The special shock-resistant and wear-resistant probe sheath material used can work reliably under high temperature, high pressure, strong corrosion, strong adhesion, strong impact, strong wear and dust.

Maintenance-free: Since the sensor has a simple structure and no moving parts, it is maintenance-free once it is put into operation.

Wide range of applications: liquid, solid, interfacial mixtures, materials can be used.

Liquid crystal display: The liquid crystal display is used for rich and comprehensive display.

No drift: No drift due to temperature or density changes in the medium.

Reliable life: Unique technology guarantees a long service life of the instrument for up to 15 years.

Technical Parameters

Applicable object: Under conditions of high temperature, high pressure, flammable and explosive, toxic and corrosive, it is suitable for liquids, slurries, powders, particles, lumps and other materials.
