For Manual Installations

• A simple Hand Air Pump (Fig. 1).

  Hand Pumps are often supplied as a back-up method of obtaining a reading in the event the compressed air/inert gas supply system is temporarily out of service. (Fig. 4).

For Continuous Read-Out with Air or Inert Gas

• Bubbling Bottle -- Bubbling Oil serves as a visual indicator of your air purge rate in addition to removing dirt and moisture from entering the system. In some systems a combination Air Filter/Regulator/Condensate Trap may additionally be required upstream from the Bubbling Bottle when plant air has particularly high moisture and dirt content. (Fig. 2).
• Tel-Flo Meter -- Tel-Flo's are designed for clean dry instrument air or inert gas systems. Clean dry air or inert gas is used where tank content purity must be maintained. A combination Air Filter/Regulator/Condensate Trap may be optionally required. (Fig. 3).

Continous readout systems use approximately .5 SCFH air or inert gas.

When tanks need to be regularly monitored, gauges are often grouped at central locations on panels. Panel mounted type "S" Tank-O-Meters (either with hand pumps or a air/inert gas manifold for one field pneumatic input connection) shipped pre-assembled from the factory are optionally available. A combination Air Filter/Regulator/Condensate Trap is normally supplied at the manifold input.

Alarm systems for panel mounted gauges are optionally available in factory assembled enclosures wired with terminal block connections. Alarms for single or multi-tank installations are mounted in general purpose or NEMA 4 watertight enclosure(s).

Panels and enclosures simplify field mounting, save time on planning installation and are a convenient way to mount all your gauges and alarms at a central location. A wide variety of wall panels and enclosures to suit your filed situations are available. Consult the factory with your requirements.

The calibrated scale is the most important part of a Tank-O-Meter^®. A computerized process for calculating, drawing and checking scales assures precision.

Calibration is based on exact inside tank dimensions, the specific gravity of the liquid being measured, along with controlled factors such as the indicating fluid used, the bore of the Pyrex manometer tube and its relationship to the well.

Each scale is serialized for positive identification. All application and calibration data is permanently retained in our vaults for future reference.

The accuracy of a Tank-O-Meter^® gauge is equivalent to or better than the minimum resolution shown on the scales. Scale resolution is typically every 1/10", 1/8", 1/4", or 1" of tank depth. Any engineering units of depth, weight, volume, or pressure may be used.
