Features

Dirt-resistant Display & Safer Switch Placement

By placing the switches on the back of the display:

• Display size is maximized
• Prevent erroneous operation from accidentally touching the switches
• Switch operation can be done without touching the front display: the display will be kept clean
• Highly durable against oil with the back material made of glass reinforced resin

User-Friendly Front Cover Structure

The front cover latches on the indentation on the body

• Unlike hinges, the front cover can be fixed at desired position (top or bottom)
• Prevent losing or dropping the cover during battery replacement

Easy Battery Replacement

Battery replacement made easy without the need to remove the meter from the pipe.

Rich and detailed display

Adjustable Register AngleRegister angle is adjustable over a 150° range

• Display angle can be adjusted to easy-to-read position regardless of installation location
• Easy to re-adjust the display angle even after changing installation orientation or location

Extensive Output Capability and Reinforced Protection

Improved electronic circuit while maintaining the reasonable price

• 4 kinds of output specifications available: pulse output,
analog output, alarm output, and analog+pulse/alarm output
• “Overcurrent prevention circuit” added to power/output circuit protects
the meter from current overload due to erroneous wiring

Complete Compatibility with the Previous Model

Retrofitting the new electronics unit on an existing FLOWPET is easy without the need to remove the meter from the pipe.
