M6200
Four Bolt Gauge for Pressurized Tanks, Columns or Vessels up to 300 PSIG
Application
M6200 Series gauges are widely used to measure liquid levels of fuels, hydraulic fluids, refrigerants, lube oils and cryogenic products in pressurized tanks, columns or vessels up to 300 PSIG [20,7 Bar]. Stainless steel mounting bolts are optional.
General Information & Features
Direct-reading fractional dials, gear actions and aluminum floats are standard models. Remote-reading TwinSite® senders are available for some models. Lever actions are available for centerline mounted models. Nitrile rubber floats are optional. Please refer to instructions on “How to Order” on reverse side of this technical data sheet.
Documents
Data Sheet
Please furnish tank drawings and switch points so proper gauge and
calibration can be supplied. Other switches available, see DS-364.
Extra Cost Option
1.For a nitrile rubber float, suitable for pressures up to 50 PSIG maximum or 250 PSIG maximum (specify if over 50 PSIG) in place of standard aluminum float, change prefix “M” to “N”.
2.For lever action on C/L mounted gauges only, instead of gear action, add prefix ”L” to the model number.
3. Neoprene Senior gasket, part number 15-836.
4. Viton Senior gasket, part number 15-415.
5. Teflon Senior gasket, part number 15-401.
General Specifications*
Mounting
Gear-action gauges are suitable for top, side, end or angle mounting. Lever-action gauges are suitable for centerline mounting on flat end of tank only.
Accuracy
Accuracy depends upon proper gauge sizing. Junior and Senior dials are ±6%, TwinSite® dials are ±10%. Accuracy may be less for some tank shapes and sizes. Accuracy may be less near full and empty. Accuracy may be less if tank is not level. This gauge is not to be used for filling. All accuracy estimates are expressed as a percent of full scale.
Temperature
Standard operating temperature range -40°F to 158°F, -40°C to 70°C with optional stainless steel mountin bolts which maybe required for temperatures below -20°F, -29°C.
Humidity
For high humidity and marine application, painting of exposed portion of gauge, less dial, is recommended.
Shock
Passes MIL-S-901 B Naval Standard Shock Test.
Vibration
Passes MIL-STD-167 Naval Standard Vibration Test.
Power
0.5 watts maximum for TwinSite® versions.
Tank Pressure
Up to 300 PSIG [20.7 Bar] with standard aluminum float and steel mounting bolts; up to 450 PSIG [31 Bar] with standard aluminum float and stainless steel mounting bolts.
Approvals
Model M6200 direct indicating gauges are available with UL listing for flammable liquids. Models M6253 and M6283 are UL recognized refrigeration components.
