and trigger critical alarms. The accuracy and dependability of the sensor gives the assurance of uptime while drilling. Sensor Types Used: Buoyancy (float), optic, capacitance, and ultrasonic point level switches, plus buoyancy, ultrasonic, and magnorestrictive continuous level transmitters.
Additional Oil and Gas Level Sensing Applications EFFLUENT TANKS: Offshore platforms must protect the oceans from contaminating materials that collect on the platform. Rain drainage The new look of oil and gas drilling. This is now a high-tech discipline dependent upon a wide variety of carries these contaminants off the platform, sensors and controls to extract the resource while protecting the environment. where they are captured in effluent tanks. This wastewater is then transferred to special containers and disposed of. Reliable level sensing is illustration in Fig. 1 shows buoyancy-type level tably leaks. Level sensors in the oil supply tanks a key element in the prevention of effluent tank transmitters fitted with floats targeted to three provide continuous monitoring and ensure overflow and environmental contamination specific gravities that identify the water, oil, and operational integrity and safety. that can lead to costly fines and cleanup. emulsions boundary layers.

The new 955 eBrik linear displacement transducer.
Price and performance so well balanced, it just might displace potentiometers. At last, there’s a purely electronic solution to position sensors. Our new 955 eBrik uses magnetostrictive technology so there’s no contact, no moving parts, nothing to wear out. No erratic position signals. Available in 1" to 72" stroke lengths, it’s economical and versatile enough for many applications, field-programmable, and the perfect replacement for old-style potentiometers.
