Indicator Scales |
N/A
The critical factor affecting accuracy of the indicator is the readout scale. KING-GAGE® scales are computer calibrated according to tank capacity curves (or from wet calibrations) to provide precise level indication for a specific tank. These scales can be graduated in practically any unit of measurement desired. In fact, 2-unit scales can provide a combination of weight, volume or depth indication. The size of the indicator (column height) is governed by the length of scale required. The combination of scale length and type of indicating liquid determines the actual pressure range of the indicator. Overall scale length can vary based on the range and resolution desired for the gauging application. Three types of indicating liquid are available. Mercury (silver) is best suited for deep tanks such as silos and provides the maximum pressure range. No. 294 (red) provides excellent visibility and works for most typical tank applications. No. 175 (purple) is the lightest fluid and is generally used for shallow tanks or special applications. |
Determining Scale Range |
N/A
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. |
Overflow Check Valve |
N/A
Included as standard with all indicator packages. Prevents escape of liquid through the top of the tube should the indicator be overpressured. This float-type check valve is included with either the KING-GAGE® or Multi-Tube Indicators. |
SafeGard Control |
N/A This unit is an adjustable pressure-limiting control that prevents overpressuring of the indicator. Available as a separate component or can be ordered as part of a KING-GAGE® pneumatic sensor package. |
ClearGard Fluid |
N/A Designed for use with mercury, this specially formulated liquid silicone imparts a non-stick coating to the inside of the glass tube. Simply place a few drops to the top of the mercury column to prevent unsightly deposits from forming that could obscure the display. |
Additional Information |
N/A
Working as a frictionless hydrostatic balance, these indicators have none of the mechanical parts common to most gauges. This makes the KING-GAGE® Indicator an inherently accurate and extremely rugged device. Used in conjunction with a pneumatic 1:1 output sensor, the indicator accepts a pressure signal that is directly proportional to tank depth. Unlike electronic indicators or meters, KING-GAGE® pneumatic indicators are inherently safe. Even in areas designated continuous explosion hazard, there are no intrinsic safety devices required. These indicators are in use worldwide and have proven their dependability over decades of service. Pneumatic column indicator has tube with liquid fill that rises in proportion to tank level. Graduated scale indicates corresponding weight, volume or depth of tank contents. KING-GAGE® Indicator uses a pair of scales mounted on either side of the glass tube. 20 in. range scales in two units (pounds, gallons). Multi-Tube Indicator has a single scale mounted behind the glass tube. 30 in. range marked in one unit (pounds). |
