OVERVIEW
TOKICO has a long history of producing high quality fl ow meters since 1950 in the fuel measuremen t field. Our
flowmeters are used in a wide variety of applications including measuring of boiler fuel oil and diesel oil, as well as for transactions for kerosene, light oil and heavy oil. We have been serving numerous customers with accurate, compact, and excellent durability fl owmeters.
Features
a. High accuracy : Accuracy is within ±0.5%, Fluid is directly measured by gear or roots, enabling accurate measuring.
b. Compact design : The fl owmeter is compactly designed, yet the indicator is easy to read.
c. Excellent durability : Simple structure enables long term durability with virtually no degradation of accuracy.
Type
a. FGB Type : Size :15mm (1/2B) ～ 25mm (1B) , Suitable for small volume fl ow between 40 ～ 3000L/h, Employs gear-type rotors made of resin
b. FRO Type : Size : 40mm (11/2B) ～ 50mm (2B) , Suitable for medium volume fl ow between 0.8 ～ 15 m3 /h (800 ～ 15,000L/h) , Employs roots rotors made of aluminum alloy, Roots rotors rotate without physical contact ( Extremely low pressure loss, Accuracy remains unchanged over a long period of time )
c. FRP Type : Size : 80mm (3B) ～ 100mm (4B), Suitable for large volume fl ow between 0.6 ～ 130m3 /h, Employs roots rotors made of cast iron, Roots rotors rotate without physical contact ( Extremely low pressure loss, Accuracy remains unchanged over a long period of time )
Precautions on piping and operation
a. Dirt and particles inside the piping cause problem to the flowmeter. Take special care when installing to new piping, since new piping may have welding debris.
b. A strainer must be installed at the up-stream of the flowmeter, as shown in below figure. This is to prevent the problem stated in (1) above. Also, prepare a by-pass line for the convenience of flowmeter disassembly and maintenance.
c. Indicator must be installed at eye level and must not face upwards.
d. Indicator must be installed at eye level and must not face upwards.
e. Use the flowmeter within the specification written on the name plate.
