Compressed air supply that is clean dry and oil-free is required for operation of the system. Under normal operating conditions, supply pressure required is 55-60 psig.

Infinite based on type of indicating liquid employed.

Well-type manometer acts as a frictionless hydrostatic force-balance. A liquid fill is raised in direct proportion to the magnitude of pressure applied. (Varies based on type of indicating liquid employed)

The KING-GAGE® system uses hydrostatic pressure measurement to determine liquid level. This pressure is created by the actual depth of liquid above the measurement point. Individual indicator scales are calibrated to the pressure range (depth), density (specific gravity) of the liquid and the volumetric capacity of the tank or compartment.

The KING-GAGE® indicator works as a frictionless hydrostatic force balance. Within the glass display tube, a liquid fill rises in direct proportion to the magnitude of pressure applied. The indicating liquid used determines the actual pressure range of this instrument (refer to Determining Scale Range).

Bubbler (Downpipe) System - uses air to purge an open ended pipe extending down into the tank. Engaging the hand pump introduces a flow of air into the downpipe. Pressure is created as liquid is purged from the downpipe, increasing until an equilibrium point is reached (air pressure = hydrostatic pressure). Equilibrium is maintained by excess air escaping through the bottom of the downpipe (and bubbling up through the tank contents).

The resulting downstream pressure (within the pipe) is directly proportional to liquid depth. As depth increases, so does pressure. Conversely, as depth decreases, downstream pressure is equally reduced as excess air flows out the immersed end of the pipe.

Each system scale is individually calibrated and custom marked in any specified unit of measurement (depth, total weight or volume). An optional 2nd scale unit can be included to combine different measurements such as depth and volume. Scales are manufactured for the individual tank geometry and specific gravity of tank contents. Due to the factory calibrated scale, the KING-GAGE® Tank Level Indicator can be used for almost any kind and shape of tank.

Scale markings include:

• Tank Designation
• Tank Units of Measure
• Product Density
• Tank Indicating Liquid
• Serial Number

Overall length of the scale can vary depending upon the range and degree of readability necessary for the application. This "readability" refers to the minimum readable change in liquid depth that can be observed at the indicator.

Three factors must be applied to determine scale length:
1 - maximum tank depth
2 - specific gravity (density) of tank product
3 - type of indicating liquid (scale factor)

A simple calculation using these factors will yield the minimum scale length required:
D (depth) x G (sp. gr.) x L (liquid scale factor) = Scale Length

The resulting value represents the scale sizes available for the type of indicator and select one that will accommodate the calculated length for your application.

On the Model 5992, a manually operated pump introduces air flow through the system tubing to purge the downpipe. This permits on-demand measurement of liquid depth without having to continuously bleed air into the system. The hand pump eliminates the need for a compressed air supply.

Model 5993 requires a compressed air supply of 55-60 psig. The rotameter should be adjusted so that the float is set at the specified markings. The air flow rate is typically between 2-5 scfm.

• All pneumatic (non-electrical) operation

These industrial tank level indicating systems have been proven over decades of use. Based on the principle of the U-tube manometer, they work as frictionless hydrostatic balances. The known weight (or mass) of the liquid fill of the gauge is balanced against the pressure created by depth of liquid in a tank. Compared to other mechanical systems, there are no floats, gears or springs that might wear or bind. This makes these simple indicators both rugged and reliable.

An acrylic rotameter controls the flow of compressed air to the downpipe in the tank. The continuous air flow purges the liquid from the downpipe creating air pressure equal to the weight of liquid corresponding to depth. The system provides continuous indication of liquid level and can be remotely located several hundred feet away.
