A heat exchanger draws vapor from the upper part of the fractionation column, cools it into a liquid, and pumps it into a liquid receiver (reflux tank). The liquid is then drawn from the bottom of the receiver by a reflux pump, a portion of which is pumped back (reflux) and reintroduced to a lower point in the column. This reflux process improves separation in the fractionation column by ensuring that enough liquid flows down to satisfy the vapor as it rises.

challenge:

Accurate and reliable liquid level monitoring and control is necessary for the reflux receiver as the distribution point for reflux and fractions in order to prevent excessive reflux from being returned to the column.

● RF2000 series guided wave radar level meter

The manufacturing technology of RF2000 series guided wave radar level gauges all come from our company. After years of demonstration by radar liquid level experts, the quality and quality are guaranteed in all aspects; RF2000 series guided wave radar level gauges have various forms and installation methods, which are almost suitable for The measurement of the entire liquid (interface) surface can also be applied to the measurement of dust, flour, sand and granular materials, which can completely replace the use of buoys and magnetic liquid level gauges; it has many advantages, such as during the measurement process, Its measurement accuracy is not affected by changes in medium density, temperature, pressure, etc.; it also has simple installation and debugging methods, and it can be used only by inputting configuration data. It is a relatively advanced liquid level instrument and is widely used in petroleum , chemical industry, electric power, metallurgy, pharmaceutical, food, oil and grain storage and other industries.

Features:

● Two-wire DC 24V power supply with low power consumption and HART communication protocol.

● Transmitter head has good compatibility and high stability.

● The performance is not affected by the change of technological conditions such as the specific gravity of the medium, the dielectric constant, and the temperature within the specified range.

● The coaxial antenna (probe) assembly has a unique sealing form, no leakage, high pressure resistance, not easy to aging, and long life.

● The double-rod probe will not affect the correct measurement when part of the material hangs on it, and has high measurement accuracy.

● RF2000 series transmitters can measure medium with extremely low dielectric constant which cannot be measured by traditional guided wave radar.

● RF2000 series transmitters are suitable for medium liquid level measurement under high temperature and high pressure working conditions.

● The length of rod type probe rod can reach 0.5~6m, and the length of cable type probe rod can reach 21m

● The transmitter part (meter head) is interchangeable, and the maintenance is more convenient.

● The zero position and range can be adjusted locally, or remotely adjusted through a remote handheld operator, desktop or portable computer.
