Why use a sight glass level gauge?

Sight gauges are a very effective and simple way to show the contents in a tank or vessel with a clear tube or reflex glass directly showing the liquid level.  Sight gauges have a low upfront purchase cost.  There are long term costs and issues associated with sight gauges, click below for more information on choosing a level device.

Sight Glass Gauges

Suitable for aggressive applications and widely used on boiler applications with steam, using borosilicate glass they provide a direct indication of the contents level and are often used alongside level transmitters to provide workers around the vessel with an instant visual indication of contents.  They can also be used to quickly verify transmitter readings.

 

The main part of a glass gauge is the body which supports and protects the glass.  The body can easily be fitted with valves to allow isolation from the tank and easy removal.  Reflex gauges are a version of glass indicators fitted with special optics to allow direct viewing of clear liquids.

  • Direct reading of level
  • Continuous indication without power
  • Suitable for aggressive liquids
  • Used widely in chemical industry, petrochemical, oil and gas, shipbuilding, power
  • Works well with steam

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 fuel efficiency monitoring

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.

Refuelling Control Valve and Dry Break Coupling

The Refuelling Control Valve is a float operated servo valve, designed to limit the amount of liquid fed into a tank to a specific level.The coupling prevents fuel leakage when fuelling a locomotive and automatically closes when the fuelling hose coupling is removed.
