Accuracy is within ±0.5%
Fluid is directly measured by gear or roots, enabling accurate measuring.
The fl owmeter is compactly designed, yet the indicator is easy to read.
● Excellent durability
Simple structure enables long term durability with virtually no degradation of accuracy.
Precautions on piping and operation
(1) Dirt and particles inside the piping cause problem to the fl owmeter. Take special care when installing to new
piping, since new piping may have welding debris.
(2) A strainer must be installed at the up-stream of the fl owmeter, as shown in below fi gure. This is to prevent the
problem stated in (1) above. Also, prepare a by-pass line for the convenience of fl owmeter disassembly and
(3) Indicator must be installed at eye level and must not face upwards.
(4) Make sure to align actual fl ow direction with fl owmeter’s fl ow direction.
(5) Use the fl owmeter within the specifi cation written on the name plate.
