● Switch type

: Self-holding type reed switch● Contact capacity: AC, DC10VA / 10W (Load resistance)

1. Liquid services subject to impulse pressure in the process.

Max.voltage of output contact:AC120V, DC170V

2. Secondary accidents might occur due to the breakage of glass inMax.current of output contact:AC0.25A, DC0.25A

such services :(Be careful of inrush current, surge voltage, etc.)• Toxic fluids such as poisons, stimulant and narcotics● Alarm setting accuracy : ⫾2% F.S. ⫾2% F.S. (of the flow rate)● Reset span

: Within 15% F.S. ⫾2% F.S. (of the flow rate)● Construction: Waterproof● Paint color: Munsell 7.5BG4/1.5 (except for the SUS body)• Flammable fluids• Explosive fluids
3. Gas handling process where breakage of glass might result in gas
leakage or scattering of glass fragments.
4. The installation places of the flowmeters where breakage of glass
might be caused by the accidents from the surrounding piping orequipment.
5. On-off operation where breakage of glass might be caused by thecollision of the float inside meter due to the abrupt change of flow.
6. Services where the heat shock by abrupt change of temperature
is expected.
