Technical Parameter

Product Introduction:

Measurement principle of Oil-water interface meter: Radio frequency admittance is a level control technology developed from capacitive type, which is anti hanging and has wider applicability. It is an upgrade of capacitive level technology.

The Oil-water interface meter is suitable for continuous measurement of material levels in liquid, particle, and block material warehouses in various industries. The oil-water interface meter is suitable for measuring in environments with high temperature, high pressure, strong corrosion, strong adhesion, strong impact, strong wear, and high dust, which is incomparable to other types of level meters. The Oil-water interface meter is used in industrial and mining sites and is suitable for most applications. The instrument consists of a circuit unit, a set of explosion-proof casing, and rod or cable type sensing elements. There are various models of sensors available, and the Oil-water interface meter can be installed as a whole or separately.

Working principle

Oil-water interface meter, also known as radio frequency capacitance level gauge

Working principle of Oil-water interface meter:

The working principle is based on radio frequency (RF) capacitor technology. Apply a radio frequency to the probe and determine through continuous analysis

The impact caused by the surrounding environment. Due to the fact that all materials have a dielectric constant and their conductivity is different from that of air, the total impedance reflected by the small capacitance offset when the Oil-water interface meter probe comes into contact with the material changes. Because the energized probe and container wall form the two plates of the capacitor, the insulation of the probe and the surrounding air become dielectric materials. When the air (with a dielectric constant of 1.0) is replaced by any other material (with a dielectric constant>1), the change in capacitance value causes a change in impedance. This impact is affected by

After circuit measurement, it is compared with the reference benchmark established by the sensitivity device setting (circuit).

Oil-water interface meter is suitable for measuring the liquid level (material level) of conductive and non-conductive liquids (solids) under pressure in pressurized vessels. Adopting a two wire system for power supply, outputting 4-20mA and overlaying a HART digital signal, while also displaying the liquid level locally. Oil-water interface meter can convert various changes in liquid level parameters into standard current signals, which can be remotely transmitted to the operating room for centralized display, alarm or automatic control by secondary instruments or computer devices.

Oil-water interface meter can be used for continuous detection of liquid level, material level, or material level under special conditions such as high pressure, high temperature, strong corrosion, easy crystallization, anti blockage, anti freezing, and solid powder and granular materials. Oil-water interface meter can be widely used for detection and control in various industrial processes.

Product Features

4-20mA/RS-485 multiple signal outputs, convenient for different system configurations.

Oil-water interface meter is suitable for level measurement of high-temperature and high-pressure vessels, and the measurement value is not affected by the temperature, specific gravity, shape and pressure of the measured liquid, as well as perfect overcurrent, overvoltage, and power polarity protection.

Anti adhesion

Advanced anti adhesion circuit design can eliminate material adhesion and generate false error signals

Strong adaptability

Oil-water interface meter can detect solid and liquid materials in situations of high temperature, high pressure, large dust, and high viscosity, without being affected by the dielectric constant of the measured medium

One click calibration

Due to the use of digital circuits, users can complete calibration at once in an empty warehouse state

Oil-water interface meter installation and debugging are simple

The fully sealed integrated installation structure has no mechanical movable parts, high reliability, and is basically maintenance free. Once installed, there is no need for multiple debugging.
