Flex-Tube Well-Type Manometer1

Dwyer Flex Tube Well Type Manometers are designed to meet the need for a direct reading single column instrument providing highly accurate pressure readings positive negative or differential Unlike other makes Dwyer manometers have no hidden wells or packing glands These instruments are constructed of shatter proof clear plastic tubing permanently bonded to well assemblies with leak proof glued joints Well assemblies are precisely machined from solid acrylic plastic Overpressure safety traps assure protection against loss of fluid Heavy pure white acrylic plastic scales have sharp black silk screened figures and graduations sealed with clear mylar coating Scales are adjusted with quick acting positive mechanism Heavy heat treated aluminum back plates have durable gray hammerloid finish These manometers are rated to 100 psig 6 89 bar Not recommended for vacuum service beyond 5 Hg 68 w c SERIES NO 1230 MANOMETERS wall mounting type Have mounting holes for easy installation They may also be used as portable manometers and can be hung or attached to any vertical steel surface by magnetic mounting clips All parts are fully visible and readily accessible for cleaning SERIES NO 1235 MANOMETERS panel mounting type All pressure connections are made from the back with the micrometer zero scale adjustment in front at the base of the liquid column MULTI TUBE MANOMETERS of the same design as the No 1235 series are available with any number of tubes mounted on a single panel They are designed for semi flush panel mounting with all pressure connections made from the back Reading columns are on 1 1 2 centers EXAMPLE 1230 8 W M B Series 1230 8 WM B Wall Mount Flex Tube Well Type Manometer range 0 8 w c using water mercury with type B connections SERIES 1230 1235 Wall Mount Flex Tube Well Type Manometer Panel Mount Flex Tube Well Type Manometer RANGE 8 12 16 20 24 36 20CM 30CM 40CM 50CM 60CM 90CM 0 8 w c 0 12 w c 0 16 w c 0 20 w c 0 24 w c 0 36 w c 0 20 cm w c 0 30 cm w c 0 40 cm w c 0 50 cm w c 0 60 cm w c 0 90 cm w c FLUID W M D Water Mercury Red Gage Oil 826 specific gravity OPTIONS B C D E AT NIST 2 molded nylon rapid shutoff tubing connectors 9 of rubber tubing and 1 brass terminal tube 2 1 8 pipe thread openings 2 compression fittings for 1 4 O D copper or aluminum tubing 2 3 way vent valves 1 8 1 8 NPT to 1 4 metal tubing Aluminum Tag NIST Certificate of Calibration ACCESSORIES A 101 3 4 oz dispenser bottle of red gage oil 826 sp gr A 102 4 oz bottle of red gage oil 826 sp gr A 103 1 pt bottle of red gage oil 826 sp gr A 104 1 qt bottle of red gage oil 826 sp gr A 126 3 4 oz dispenser bottle fluorescein green color concentrate
