Water drain pollution

The water drain version of our density valve is a simple mechanical product that prevents the discharge of contaminated water.  It can be used on its own or as a back up device in case of electronics failures.

Preventing Chemical Leaks

Using a PVDF or other plastics to suit, our density sensitive valves can also be used with aggressive fluids which attack metals.  The valve can be installed on drain lines in a plant to ensure that any water is not contaminated when being discharged.

Density Sensitive Valves – Gravity Fed

A simple device with an internal float that prevents fluid flowing through when the density of the fluid changes.  Sensitive up to a 1% change it can be used in a range of fluid applications to ensure fluid quality. 

 

Designed for use in discharge lines to rivers, onboard ships which discharge water overboard, drain lines of bulk fuel storage tanks and in a range of separator applications.

Mechanical in operation and requiring no power, this simple technology that is easy to maintain can be fitted as the main prevention technology, or as backup to existing electronic systems.

    • Saves valuable product
    • Prevents pollution
    • Low system cost
    • Simple operation
    • Easy to maintain
    • Robust and built to last

Density Sensitive Valve – Pumped System

Designed for use as a fuel grade monitor using our servo valve bodies, this float operated thornton pilot automatically shuts off when the wrong grade of fuel is detected to prevent delivery of low grade fuel or fuel into the wrong tank.

 

Suitable for use with any fluids, the valve and pilot combination monitors the fluid going into the valve and uses floats in the pilot to create a pressure, automatically shutting off the valve if the wrong fluid density is detected.

Installed applications include airport fuel delivery to storage tanks, fuel delivery at fuel storage terminals and mixed product storage facilities.

    • Simple and robust
    • Mechanically, float operated
    • Self-contained, no power needed
    • Isolates flow when wrong density detected
    • Sensitive up to 1% change in density

Train level measurement, gauges and indicators

To solve a specific problem with access and the lack of height between a fuel tank and the trains body, AMS have modified the head of our approved level sensors to allow fitting in confined spaces. This development also removed the need for the transmitter to be located in a separate box on the side of the tank and allowed the sensor to be wired directly to the indicators, saving significant additional costs in materials and wiring time.

Train level measurement and control

Advances in the way instrumentation can be powered due to processing capabilities at reduced power levels, combined with the ever-continuing miniaturisation of electronics capability, has created the opportunity for rail companies to consider more modern electronic/digital technology as an alternative to the traditional methods for level measurement.
