General Description
Make sure the power supply is OFF before carrying out work on the wiring
or inspections involving disassembly. If such work is carried out with the
power on, there is a danger that equipment may malfunction or electric
shock may occur, leading to injury or other accidents.
Make sure that wiring work requiring a special license is carried out only
by qualified personnel. If carried out by unqualified personnel,
overheating or short circuits leading to injury, fires, damage or other
accidents may occur.
Do not touch the terminals during transmission. Failure to observe this
precaution could result in such hazards as damage to the product,
malfunctions, electric shock or fire.
This vortex flowmeter counter is built around a single-chip microprocessor and is
lightweight and compact in design. It offers four independent functions (cumulative
total flow, instantaneous flow rate, hourly and per-minute total flow and resettable
total) in a single unit. Optional 4 – 20mA DC and 1 – 5V DC flow rate outputs are
also available.
