Penberthy – Magnetic Liquid Level Gages

Rugged, Versatile Options for a Wide Range of Applications      MULTIVIEWTM Magnetic Liquid Level Gages utilize a communicating chamber constructed of 2-1/2″ pipe which is connected to the process tank with either side or end connections. A float with a self-enclosed magnet is custom sized and weighted to float at the surface of the process liquid to be monitored. The float is then installed in the communicating chamber. The industry-unique concentric magnet in MULTIVIEWTM gages provides a more consistent magnetic field than conventional magnet designs. Choose between Follower or Flag style indicators. Non-Intrusive Analog and Digital Level Transmitters with HART and Foundation Fieldbus protocol as well as High & Low Level Switches are available as standard options.

Low Pressure Flat Glass Gages

For less demanding process conditions. Penberthy’s low pressure gages are designed to maximize the mechanical and economical advantages of ductile iron covers. All materials in low pressure gages conform to ASTM specifications. RL gages can achieve pressures to 2400 psig [16550 kPa] @ 100ºF [38ºC] and TL gages can achieve pressures to 2000 psig [13790 kPa] @ 100ºF [38ºC] when manufactured with size 1 glass – see ratings table below. Penberthy does not recommend low pressure gages for steam/water applications.  Model RL – Reflex Low Pressure | Model TL – Transparent Low Pressure 

Medium Pressure Flat Glass Gages

For most common process conditions. Strength and versatility make Penberthy’s medium pressure gages ideal for most common process conditions. Offshore specification 2600.1 is preferred with medium pressure gages in offshore and other corrosive environments. All materials in medium pressure gages conform to ASTM specifications. RM gages can achieve pressures to 3000 psig [20680 kPa] @ 100°F [38°C] and TM gages can achieve pressures to 2500 psig [17240 kPa] @ 100°F [38°C] when manufactured with size 1 glass – see ratings table below. Although not designed for thermal cycling, Penberthy allows use of medium pressure gages for steam/ water applications due to historical precedence – see Application Report 2781 in Penberthy Catalog. Model RM – Reflex Medium Pressure | Model TM – Transparent Medium Pressur

High Pressure Flat Glass Gages

Heavy duty construction for high pressure resistance. Penberthy engineers its high pressure cover to allow maximum rated pressure regardless of glass size. High pressure gages resist torsional stresses exceptionally well to provide a process gage for the most demanding applications. All materials in high pressure gages conform to ASTM specifications. RH gages can achieve pressures to 4000 psig [27580 kPa] @100°F [38°C] and TH gages can achieve pressures to 3000 psig [20680 kPa] @ 100°F [38°C] for all glass sizes – see ratings table below. Penberthy does not recommend high pressure gages for steam/water applications. They are designed for high pressure, but low thermal cycle duty.

Gagecocks: Flat Glass and Tubular Glass

Offset and straight pattern designs for flat glass and tubular glass gages Penberthy offers offset and straight pattern gagecocks that isolate the gage chamber from the liquid contents of the vessel. Offset gagecocks have an advantage of permitting the inside of the gage glass to be cleaned easily with a minimum of disassembly. By removing the vent and drain plugs (or other connection), a straight passage through the gage chamber is opened. A brush can be inserted through the gagecocks vent and drain for glass cleaning. To prevent rapid loss of fluid in the event of accidental glass breakage, Penberthy supplies its gagecocks with automatic ball check shut-off. Should the glass break, the pressure drop causes the ball checks to seat to prevent loss of tank contents. To unseat these ball checks during the liquid level readings, the tip of the gagecocks stem has an extension that pushes the ball away from its seat while allowing the gage column to fill as liquid contents pass around the ball. Stainless steel retainers prevent reverse seating of balls or loss of balls during installation. Both upper and lower gagecocks in each set are equipped with horizontal ball checks. Balls are located on the vessel side of the gagecocks seat. Gagecocks with ball checks omitted meet ASME boiler requirements. As an alternative method to meet ASME boiler requirements, the lower gagecock is available with an optional vertical rising ball check located in the offset portion of the gagecocks body, and the upper gagecock has a leaky seat. Gagecocks Connections    Gagecocks Bodies  (x)30 Series – Offset Pattern |  (x)20 Series Offset and Straight Pattern 

Series 100, 200, 300, 400 and 600

These gagecocks have inside screw threads that are wetted by the liquid. They are offered with a wide range of features in both straight and offset pattern designs (600 Series — offset only).

Series 500 and 700 — OS&Y

These are outside screw and yoke gagecocks that are used for high-temperature or corrosive-liquid applications. The OS&Y design isolates the stem threads from the liquid. The stem seats in a reciprocative instead of a rotary fashion.

Series N2, K2, K3, N6 and N7

Series N2, K2, K3, N6, N7 Tubular Glass Gagecocks

Gagecocks and TubularsPenberthy

Externally mounted to the tank, tubular glass gagecocks provide direct visual verification through tubular glass. Tubular glass gages are used to register levels in low to medium pressure applications. Accessories allow you to customize each gage to your application requirements. These options provide enhanced level indication and protection for the tubular glass.
