AJD’S self-powered contents gauges require no external power to provide a continuous readout of tank contents in engineering units in vented vessels. It is available from Procon Instrument Technology Pty Ltd.
It is simple to install with both internal and external sensor mounting options.
The instrument may be fitted with up to 50m of capillary with 3m being standard. A detachable capillary option is available when the capillary is needed to pass through a wall or under a roadway, for example.
The instrument monitors hydrostatic pressure and is therefore calibrated at the SG of the stored liquid. Calibration is at a stated temperature up to 150°C.
The indicator is constructed of stainless steel and is available in 100mm, 160mm and 250mm case size.
A variety of wetted parts and connections are available for compatibility with the stored products.
Options for alarm switches or analogue re-transmission are available.
Procon has a range of self-powered tank contents gauges available for the marine market, which have been designed for many onboard applications and liquids such as heavy fuel oil, diesel and lube oils to potable, bilge and seawater.
The dial indicators are made of stainless steel and are weatherproofed. As with all marine-type gauges they are fully overload protected.
Calibration can be completed in any unit of mass, volume or height with dual scales an option.
Procon has Bureau Veritas certification for the Internal Sensor type (IM) and the Bulkhead/Gland system which, if required, allows the indicator to be mounted in a separate compartment away from the tank.
The bulkhead coupling only requires a 38mm diameter hole in the bulkhead and with the use of the sealing washer the coupling can be fitted along the capillary of a bulkhead gland once the capillary has been passed through.
At the time of manufacture, the gauge capillary is fitted with bulkhead glands at pre-determined points. Once the capillary has been passed through and the coupling and gland have been aligned, it can be secured in place using the nut and compression washers of the bulkhead coupling. The bulkhead will then retain its gas and watertight integrity. If required, this system can be fitted into several bulkheads.
Procon have a range of gauges to suit a wide variety of industries.
