Midget Model 277 Pneumatic Indicator

Midget,Model 277,Levelometer,Midget,Model 277,Levelometer,Ktech,Industrial,Products,IncThe Midget Model 277 Pneumatic gauge provides an economical way to achieve reliable and accurate tank gauging in vented tanks. Pneumatic gauges have been used for many years in tank gauging systems requiring remote indication with accuracy and stability over wide temperature ranges. These gauges are supplied with custom dials, depending on the application. Dial scales may be manufactured to indicate proportional (i.e. E, ¼, ½, ¾, F), litres, gallons, feet & inches, percentage of full and dual scale.

The Model 277 Midget Levelometer is recommended for tank capacities up to 5000 gallons. The maximum tank height is 10 feet. Its 3 ½" (90°) dial provides up to 50 graduations and is generally accurate to ± 2%.

Ktech is pleased to announce that our Midget 277 Levelometer is now certified to following standards:

1. ULC/ORD-C180-97 Liquid Level Gauges and Indicators For Fuel Oil and Lubricating Oil Tanks

2. UL 180 Standard of Safety: Liquid-Level Gauges for Oil Burner Fuels and Other Combustible Liquids

The Model 277 Midget Levelometer is suitable for tanks up to 12 feet high. Its 3 ½" (90°) dial provides up to 50 graduations and is generally accurate to ± 2%.

Theory of Operation

The Midget Model 277 provides an intermittent capacity reading for vented tanks. The tank assembly is 3/16" copper tubing with an air chamber at one end. The tubing assembly is inserted into the tank until the air chamber touches the bottom. The other end of the tubing is connected to the tube fitting on the Midget gauge. The hand pump provides the source of air. Air is pumped through the tubing into the tank. The back pressure caused by the column height of liquid in the tank causes the gauge pointer to move and indicate the capacity of liquid in the tank. The gauge must be pumped again and another reading taken. When two consecutive readings are the same then an accurate measure has been obtained.

Installation

Straighten out air chamber end and insert straight through tank opening until it touches bottom of the tank. Screw reducing bushing and compression fitting which forms a tight joint between the tubing and the reducing bushing. These fittings are on the tubing in order of attachment. Then run the tubing to the desired gauge location, cut to length and connect tubing to the gauge end. Attach communicating tubing to wall to prevent it from being damaged.

WARNING

Failure to make the following adjustment will result in improper gauge reading. Be sure the pointer indicates the first mark on the dial before attaching the tube to the gauge head. If it is above or below this mark remove plug from the bottom of the case. Insert screwdriver vertically through the hole and engage it in the slot of the self-locking adjustment screw. If the pointer is below the first mark on the dial, turn screw clockwise, if above, turn screw counterclockwise. Reinsert plug and attach tubing.

To read correct level, pump gauge, take a reading. Pump again, take a reading. Pump and take a reading until two readings are the same. Gauge indicates correct tank volume now.
