Wireless Wellhead
It has long been the desire of operators to limit the amount of wiring around the wellhead and associated separators, tanks and flow measurement equipment found at a distance on the pad. In recent years the use of Accutech battery-powered sensors has become common for measuring wellhead pressures and for monitoring plunger arrival in artificial lift installations. However, much to the frustration of operators there was one remaining component that required either a line-powered or a dedicated solar-powered system the sales valve.
With the introduction of the VC10 Valve Controller, Schneider Electric’s Accutech line of battery-powered sensors and controllers are the only way to realise a complete wireless wellhead solution certified for a Class 1 Div 1 environment. Coupled with Accutech level sensors and SCADAPack flow meters the Accutech product line offers the most cost-effective way to instrument an entire well pad.

Valve Control
The Accutech VC10 Valve Controller is ideally suited for wellhead installations or may be used to wirelessly control pneumatic valves in general industrial applications. Its integrated pressure and plunger arrival sensors, couples with an optimized powe system, provide valuable diagnostics to operators and reduces maintenance and operational costs.
Features include:
Battery-powered wireless pneumatic valve controller
Self-powered with up to 50,000 actuations before battery replacement
Pressure transducer used for closed-loop valve control
Two digital inputs with one used as a counter for plunger arrival sensing
Energy-efficient 2-way solenoid valve with self-optimising pulse width and retry logic
Configurable valve control state for sensor power-up and failsafe conditions

Flow
The Differential Pressure Field Unit may be operated in any one of four modes: Differential Pressure, Orifice Flow, Open Channel Flow and Level, and may be configured with a 22-point custom curve capability. The product also has a square root function for use with orifice plates, v-cones, and pitot tubes, providing volumetric flow measurement.

Level
The SL10 and GL10 wireless tank level field units use a submersible pressure sensor to provide hydrostatic level of a vented tank or well. Specific-gravity correction and all common level units are offered.
The DP20 is ideally suited for level applications in pressurised tanks, such as propane & butane tanks.

Analog and Digital I/O
Ideal for adding wireless capabilities in remote or hazardous locations to existing or newly wired devices such as proximity switches, level switches, valve position, ultrasonic and radar level meters, or any other analog or switch input: the Accutech AI10 and AV10 wireless multi-input field units provide two analog inputs in either current (4-20mA) or voltage (0-10V) configurations. Each unit also includes two discrete contact closures.
Analog outputs and switch closure outputs are also available in a DIN-rail mounted module at the Accutech base radio.
