Balcrank Black Knight Sight Gauge, 0-99 in (4520-014)

The Balcrank 4520-014 Black Knight Universal Tank Level Gauge is a professional-grade mechanical fluid level indicator designed for monitoring lubricant levels in compatible bulk oil storage tanks, Roth double-wall tank systems, and automotive fluid dispensing equipment. Featuring a 0–99-inch measuring range, easy-to-read dial display, and 2-inch NPT male tank connection, this gauge provides a convenient way to monitor stored fluid levels without opening the tank.

Designed for automotive repair shops, fleet maintenance facilities, dealerships, heavy-equipment service centers, and industrial lubrication operations, the Balcrank Black Knight 4520-014 Tank Gauge helps technicians and shop managers track lubricant inventory and plan fluid deliveries.

The gauge utilizes a mechanical float-operated measuring system that responds to changes in the liquid level inside the tank. As the fluid level rises or falls, the float moves and the external indicator displays the corresponding fluid depth in inches.

With a 0–99-inch measuring range (8 feet, 3 inches), the Balcrank 4520-014 is designed for compatible stationary bulk fluid storage tanks. The gauge is commonly specified for Balcrank/Roth lubrication tank packages, allowing service facilities to visually monitor stored motor oil, automatic transmission fluid (ATF), and other compatible lubricants.

Its 2-inch NPT male threaded connection is intended for installation into a matching female-threaded tank bung. This provides a practical tank-mounted measuring solution for properly configured bulk oil storage systems.

Unlike electronic fluid monitoring equipment, the Balcrank Black Knight mechanical tank gauge operates without batteries, external power, or electronic sensors. Its straightforward design makes checking tank fluid levels a convenient part of routine shop maintenance.

The Balcrank 4520-014 is also commonly supplied loose with certain lubrication tank packages for installation during equipment setup. This allows installers to position the gauge according to the tank manufacturer's instructions and available mounting configuration.

Whether you're replacing an existing tank level indicator, installing a new Roth double-wall oil storage system, or improving bulk lubricant inventory monitoring, the Balcrank 4520-014 Black Knight Universal Tank Gauge provides a practical solution for professional fluid storage applications.

Important: Balcrank specifies the Black Knight gauge for stationary storage tanks only. It is not recommended for mobile lubrication vehicles or mobile fluid-handling tanks.

Why Choose the Balcrank Black Knight Mechanical Tank Gauge?

Convenient Fluid Level Monitoring

The Black Knight gauge provides a visual indication of stored fluid depth, allowing maintenance personnel to check tank levels without removing the fill cap or manually measuring the liquid.

0–99-Inch Measuring Range

With a maximum measuring range of 99 inches, the gauge is suitable for appropriately sized stationary lubricant storage tanks.

Supports Bulk Oil Inventory Management

Knowing the approximate fluid depth inside a tank helps facilities plan lubricant deliveries and reduce the risk of unexpectedly running low during service operations.

Mechanical Operation

The float-operated design does not require batteries, power cables, or electronic monitoring equipment.

Compatible Tank Bung Installation

The specified 2-inch NPT male connection provides a mounting option for compatible tank openings.

Replacement for Existing Tank Packages

The Balcrank 4520-014 is a manufacturer-listed tank gauge accessory, making it easier to identify when maintaining an existing Balcrank bulk oil storage package.

Balcrank 4520-014 vs. 4520-024 Tank Level Gauges

Balcrank offers two tank gauges with different measuring ranges.

The Balcrank 4520-014 Black Knight provides a 99-inch measuring range, while the Balcrank 4520-024 Morrison Bros offers a longer 108-inch range.

Selecting the correct model depends on the tank's internal height, connection size, and mounting arrangement.

Installation and Tank Compatibility Considerations

Before installing the Balcrank 4520-014, confirm the following:

• Tank Height: The tank's internal depth must be compatible with the gauge's 0–99-inch measuring range.

• Tank Bung Size: Verify the threaded opening accepts the specified connection.

• Stationary Installation: Use the gauge only on compatible stationary tanks, as recommended by Balcrank.

• Fluid Compatibility: Confirm the gauge's wetted materials are suitable for the stored lubricant or ATF.

• Internal Clearance: Ensure the float mechanism has adequate space and does not interfere with suction tubes or other equipment.

• Tank Calibration: Use the appropriate tank chart if fluid depth must be converted into gallons.

The Black Knight gauge reports liquid depth in inches, not necessarily the exact quantity of fluid remaining in gallons. Converting depth into volume requires the tank's dimensions or calibration information.
