New plunger arrival sensor
Mounted on the surface lubricator, the unit detects the plunger's arrival and activates the controller to the appropriate mode for gas sales or shut-in. The company says its tool's proprietary technology represents significant improvements in plunger arrival sensing.
Driven by an embedded microprocessor, the sensor continually self-calibrates to filter out environmental noise. It uses advanced 3D technology to detect the plunger's arrival. By sensing the plunger in three coils in three axes (X, Y, and Z), the sensor is able to more accurately detect plunger arrival.
The combination of the microprocessor and 3D technology enables the tool to detect arrival of the plunger traveling at any speed, even if the plunger is stopped in front of the sensor.
The unit features an aluminum housing that won't flex when installed and potted electrical components to protect against harsh weather conditions.

Kit determines methanol concentration in oil
OMMICA, a detection kit designed for use onshore or offshore, determines the concentration of methanol or monoethylene glycol in oil or water. This simple, accurate, and sensitive testing kit analyzes the concentration of the thermodynamic hydrate inhibitors in water, crude oil, and condensate.

New plant safety air devices
Two new US National Institute of Occupational Safety and Health-approved units—the PSS 3000 and PAS Lite compressed air breathing apparatuses—are suited for use in oil field plant maintenance, plant and operational safety, and emergency response.
Harnesses are made of durable materials. The PSS 3000 uses fire-retardant ethylene-vinyl acetate, while the PAS Lite uses styrene-butadiene rubber-coated webbing. These materials are 18 times less permeable to liquids than traditional materials and are nearly 100% inert to chemicals, the company points out. This durability, in addition to simple disassembly, helps reduce the time and effort required to clean and maintain the units. Workers can even do maintenance work in hazardous areas without the need for a plant shutdown, the firm notes.
