• Graphically Displays Tank Level
• Hydrostatic Manometer Principle
• Proven Dependable in Decades of Service

7750 KING-GAGE® Indicators are rugged instruments that will provide accurate and reliable liquid level measurement. Used with bubblers or pneumatic tank sensors that produce a pressure output signal, the fluid-filled indicator can provide local or remote tank level indication. Acting as a hydrostatic balance, its operation is inherently accurate and simple to maintain. A custom calibrated scale permits direct reading in units of volume, weight, or depth.

Our 7750 KING-GAGE Indicator is a precision manometric instrument.

APPLICATION NOTE: All pneumatic operation eliminates any need for additional intrinsic safety provisions.

• Low Cost On-Demand Indication
• All Pneumatic (Non-Electrical) Operation
• No External Power Source Required

Combining accuracy, low cost, and remarkable simplicity, the KING-GAGE® Hand Pump Gauge is designed for stand alone operation. No external power is needed other than to use the integral hand pump to pressurize the system. Perfect for isolated storage tanks or where only periodic readings are required. A custom calibrated scale permits direct reading in units of volume, weight, or depth.

5992 Hand Pump Tank Gauge uses the proven technology in which a length of pipe extends downward into the tank liquid. When filled with air from the hand pump, liquid within the downpipe is displaced by air pressure equal to the hydrostatic force of liquid in the tank. This pressure is read on the gauge using the calibrated scale to show tank level.

• Self-Contained Hand Pump System
• On Demand Monitoring of Tank Level
• Individually Calibrated Indicator Scale 

LevelBAR HP (hand pump) is a complete tank gauging system. This manually operated liquid level bubbler gauge provides on demand level indication for isolated tanks or situations requiring only periodic monitoring. This self contained package requires only 100-240Vac and a length of pipe extending downward into the tank to measure hydrostatic pressure due to liquid level.

The package includes a factory supplied marked scale calibrated for the density of tank contents. LevelBAR HP combines remarkable simplicity, low cost, and accuracy. Simply use the integrated hand pump to pressurize the system and obtain a tank level reading.

• Visual Display of Tank Levels
• Custom Scale for Weight or Volume
• Direct Replacement for Manometer Gauges
• 4-20 mA output signal available to PLC

The LevelBAR multi-segment LED column display includes an individualized scale calibrated to the actual tank capacity. Marked in any specified unit(s) of measurement, it permits direct reading of total liquid weight or volume. This unique analog column indicator works as a local or auxiliary remote display in new or retrofit applications.

Pneumatic input models include an integrated differential pressure (D/P) element. This allows LevelBAR to be used with bubblers or other air operated systems as a direct replacement for mercury tank gauges or other fluid-filled manometers. It even provides 4-20 mA output compatible with other receivers or to use for process control functions.

• 8 Tank Multiple Channel Capacity
• Operator Interface Display & Keypad
• RS-485 Multidrop Communications

LP2 Multiple Tank Indicators expresses tank level directly in engineering units. Referencing a capacity profile to correlate transmitter output to actual tank geometry, the indicator formats the resulting value directly as the total weight or volume of liquid in the tank. LP2 Multiple Tank Indicator provides an operator interface keypad for access to function selection and density adjustments. There are no user conversion factors involved or scaling points to enter. All application details are factory programmed into an innovative nonvolatile modular memory called the Datapack iButton.

LP2 multiple tank indicators accept up to eight input channels that receive proportional 4-20 mA signals from liquid level transmitters. The actual sensor used to detect hydrostatic pressure created by liquid depth can be either electronic or pneumatic (using an electronic pressure transmitter to convert the sensor's pneumatic signal into 4-20 mA output).

LP2 multiple tank indicators can be used to eliminate analog I/O at your PLC or PC-based control system. As data acquisition hubs, each LP2 tank level indicator provides multiple point serial communications. An expandable network of up to 32 discrete indicators can be installed on a single two wire network (RS-485) for total of 256 possible input channels. Dual serial ports support multiple network configurations including query-response communications with a computer (or PLC), remote satellite displays, or interface to a KING-GAGE® LP3 system.
