Tubular Glass Gagecocks
For cost effective level indication.
Penberthy Tubular Glass Gagecocks are used to register liquid levels in low to medium pressure applications. They are externally mounted to the vessel and use tubular glass to provide direct visual verification of the liquid level present. The transparent glass also provides an excellent means to optically inspect fluid characteristics.
Liquid enters the gage through the lower tank connection. The meniscus present in the glass tube corresponds to the liquid level in the tank. Available accessories allow you to customize each gage to your specific application requirements. These options can also provide enhanced level indication and protection for the tubular glass.
Guard Rods - Two or four metallic rods placed next to the glass tube.
Plastic or Wire Glass - A transparent box surrounding the tubular glass constructed from either clear plastic or wire glass.
Sheet Metal - Two pieces of sheet metal formed to protect both sides of the tubular glass. The front and back are left open to facilitate easy viewing.
If water is the liquid used, the stripes become horizontal. Liquids with a refractive index less than water will alter the angle less, higher indexes will alter the angles more. The refractive protector is designed for use with standard tubular glass.
Internal Tubes - A stainless steel internal heating or cooling tube that passes through the length of the tubular glass can be used in conjunction with an offset pattern valve and high pressure glass.
Glass Union - Intended for use in gagecocks over 48" in height. It allows you to join two pieces of glass within the same gage. This increases the length of the gage, yet maintains the same pressure/ temperature rating as the individual pieces of glass. Glass unions should be used in conjunction with the refractive protector to provide mechanical stability.
Hydraulic Adapters - Hydraulic Adapters are used in place of valves for connecting the gage to your vessel. They attach directly to the ends of the tubular glass, providing a 1/2" NPT male connection. This allows you to incorporate most standard hydraulic connections currently available.
