In the preheating system of the distillation column, a pre-flash tank system separates the steam generated before preheating from the heater or main distillation column. This prevents overheating of the heater from burning or pressure drop and reduces the steam load on the distillation column to avoid flooding.

Challenge:

The pre-flash tank produces a moderate amount of foam, which affects the accuracy of level measurement and reduces distillate production in the atmospheric column. Too low a pre-flash tank level will cause cavitation of the pump by the flash crude oil. Excessive liquid levels will result in liquid carryover into the distillation 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.

● The performance will not be affected by the change of process conditions such as the specific gravity, dielectric constant and temperature of the medium 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.

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

● The transmitter part (meter head) is interchangeable, more convenient for maintenance, good compatibility and high stability.

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