Solutions for Oil and Gas Production Level, Multiphase Level and Density Measurement

Applications in the Oil & Gas Industry Exploration and Production. BERTHOLD TECHNOLOGIES radiometric instruments are perfectly suited for use in the offshore and onshore oil industry. They are installed on Drilling Rigs, Production Platforms, FPSOs and Oil Terminals and provide highly accurate and repeatable readings, – the base for a profitable and safe operation. Regardless whether ■ a high level / low level alarm, a continuous level measurement, characterized by an outstanding level of sensitivity and long-term stability – reducing radiation levels and maintenance to a minimum.

Level Alarm for Safety Applications The reliable control of high level and low level set tank wall and therefore not exposed to the high points is very important for process safety in the pressure and high temperature conditions inside oil and gas production. Separators especially have the tank. Existing tanks can be easily retrofitted such a safety system that prevents from overfilling by the BERTHOLD point level systems, without any and ensures operability of following processes.

Measuring Sand Level Sand is removed from the liquids in hydrocylones or in sand settling tanks. The sand level information is very important to control the desanding process. BERTHOLD radiometric level transmitters are ideal for monitoring the sand level, because of their non-contacting nature. Depending on the individual application and requirements the measurement can be realized either with multiple point level measurements or with continuous level measurements.
