Features

• Small size of this instrument makes it easy to install in the field.
• On/Off action of the switch is very definite, owing to the paddle style flow sensor.
  This device has an extremely long life expectancy since the movement of the paddle is transmitted to the switch through a flexible bellow. (Fatigue limit of the bellows is greater than 100,000 times.)
• Unitized construction of this model reduced the parts count, and made it simpler to assemble, thus a more reliable long-term working is expected.
• "Using an ABS case" led to a more attractive design and also made it highly corrosion resistant.
