• Model 58 K consists of 3 major components
 
1) Chamber
2) Float
3) Indicator Roller Assembly
 
The chamber when installed will fill through the process connections to a level equal to that of the vessel on which it is mounted. The chamber may be constructed of a variety of non-magnetic materials and having process connections compatible to those welded on the vessel.

The Float, is located within the chamber and is specially engineered to a precise Size and weight to provide an accurate level reading. Inside the float a specially Designed magnet generates a strong uniform magnetic current.

The Indicator Roller Assembly mounted externally to the chamber and contains a series of bi-coloured rollers each with an integral magnet, that flip when acted upon by the magnetic force generated by the magnet assembly in the float. Thus the indication rollers magnetically interlock with each other and so are kept in a stable position. The float responds to changes in the liquid level and the indicator roller assembly will mirror the changes thereby providing a precise liquid level measurement.

APPLICATIONS:
Leveltrol Model 40K & 41K level gauges are designed for liquid level gauging of fixed or floating roof tanks storing oil, water, solvents and other products where a readout to within 25 mm of liquid level is satisfactory and provides the additional convenience of being able to read out at distance of 100 - 200 feet. The units are designed and constructed to permit simple easy installation on tanks in service or tanks not in service and to provide a maximum of trouble free service. They are highly recommended for applications requiring a low cost, low maintenance method for liquid level gauging.

FEATURES:
• Model 40K & 41K are float operated and have a signal red pointer cradle that runs vertically up and down registering tank contents on a 150 mm Aluminum scale that is mounted outside of the tank for quick convenient readings.
• The stainless steel construction of the float is resistant to the corrosive effect of petroleum products and assures a long dependable use.
• The float cable used to secure the float to the pointer cradle is also of SS 304 construction.
• The scale is of heavy gauge Aluminum construction 150 mm wide having controlled cross section geometry and having 1000 mm unit length.
• The pointer cradle is painted signal red to enhance visibility and has 6 Nylon rollers for friction less gliding on the scale.
• Brackets, Fittings Bolt Nuts necessary for mounting and installation are included with the supply.
• For highly corrosive non-toxic liquids float can be supplied in PP or glass.

"Leveltrol" Tubular Level Gauges are externally mounted to the vessel and use tubular glass to provide direct visual verification of the liquid level. The transparent glass also provides excellent means to optically inspect fluid characteristics.

Model 36K is provided with our standard auto shut off ball check valve. Incase of accidental glass tube breakage the balls seat to prevent loss of tank contents. These valves are suffice to isolate the liquid level gauge and eliminate the need for additional isolation ball valves.

"Leveltrol" Model 30K comprises of end connections in place of the standard auto shut off ball check valves. This model is highly recommended where choking is encountered due to the small bore of level gauge valves and is used to register liquid levels in low to medium pressure applications.

"Leveltrol" Model 35K comprises of PP end connections and is used to register liquid levels in low to medium pressure applications where metallic gauges are not compatible to the medium. They are externally mounted to the vessel and use tubular glass to provide direct visual verification of the liquid level. The transparent glass also provides excellent means to optically inspect fluid characteristics.

"Leveltrol" Reflex Level Gauges allow accurate reading of liquid levels at a glance. These glasses have a prism glass window that uses the basic optical principle of light refraction and reflection to enhance the indication of the liquid level. This lets the level of even colorless liquids be seen without close inspection. When rays of light enters the liquid space behind the groove it is virtually absorbed by the gauge body, so the liquid space behind the reflex glass appears black. Light striking the open space above the liquid level is reflected back to the observer, so that area appears silvery.

The distinct line that separates the dark and silvery areas clearly shows the actual liquid level in the system.

"Leveltrol" Model SM-BUV Side Mounted Magnetic Float Switches operate with reed switches.

These reed contacts are activated by the magnetic field of a permanent magnet in the float without wear, tear or mechanical contact.

The contact functions can be changeover or normally open. The only moving part of the float switch is the float system.

Technical Advantages
 
• Compact Construction
• Very few mechanical components
• Available in variety of materials
• Available with a variety of terminal boxes
• Very rugged for tough environments
• No regular maintenance necessary

"Leveltrol" Model TM-BUV Top Mounted Magnetic Float Switches are used to control distinct levels of a liquid. They are based on the float principle with individual contacts for every level to be monitored.

A magnet that is built into the float actuates through the wall of a guide tube, one or more reed contacts. The switching operation is without direct contact with the liquid, free of wear and tear and does not require any power supply.

Contact denomination always refers to the rising level of the liquid:

• S -closing on rising level
• O-opening on rising level
• U- changeover
• By using one float upto a maximum of two switch points the switching behaviour is bistable.
• Contacts are volt free.

The "FLOCLEAN" brand of Y Strainers manufactured by C-TRU Process Equipments is commonly used for pressurized lines but can also be used in suction or vacuum conditions.

"FLOCLEAN" Y Strainers are ideal for applications where small amount of solid particulate is expected and where clean out will be infrequent.

Whether the need is there for a simple low pressure cast iron threaded strainer or a large high pressure special alloy unit we have the Y Strainer that fits your application.

When unwanted solid material has to be removed from flowing liquids in order to protect equipment, C-TRUs "FLOCLEAN" range of strainers is the answer. Not only does the strainer protect equipment, it improves productivity by reducing maintenance and down time.

While C-TRU does offer a comprehensive line of cast strainers, sometimes, because of space limitations, the need for a special alloy, unique piping connection, cover operating system or size, a custom strainer is required. In such cases a cast strainer will just not work because often it is not easy or possible to modify the cast metal unit.
C-TRU solves these application problems by fabricating pipeline strainers to meet the requirements of any straining application.

Fabricated Basket Strainers are manufactured one at a time and are made to fit the exact requirements of the application. You never have to pay for more strainer than you need or settle for a strainer that will not quite do the job you want it to do.
