ULTRASONIC FLOW METER FOR FUEL GAS CONTROL UX40,UX50,UZ40,AICHI TOKEI VIET NAM AICHI TOKEI Vietnam Đại lý AICHI TOKEI tại Việt nam

Features

No straight pipe section required for installation

It is possible to connect the flow meter directly to a bend such as an elbow piece and a flexible pipe.

As wide as a 1:50 turn down ratio

Applicable also for measuring gas flow of a burner having a large turn down ratio.

Easy to replace batteries

Users can replace batteries without removing the meter from the piping.

Strong against dust, and high durability

Use the product in such a condition that does not allow the gas to re-liquefy into oil mist.

IP64 Protection – available for outdoor use

High temperature can cause the electronic circuit board to be deteriorated and batteries to be consumed. To avoid unnecessary rise in temperature, the product is recommended to be fitted with a sunshade.

*1 Gas type (composition) can be changed on site among those specified here with little degradation in measuring accuracy.
*2 Replaceable without removing the meter from the piping
*3 In case a distance from an elbow of minimum 10D in the upstream side and 5D in the downstream side of the meter can be secured: ±2%RD (for a range of 10% to 100% of the max. flow) and ±0.5%FS (for a range of 2% to 10% of the max. flow).
The distance to a governor should be greater than 10D for both the upstream and downstream sides of the meter. Failing to meet this condition may lead to inaccurate measurements. For other conditions for installation, please contact us.
*4 Normal flow: Conversion of measurement into a flow at 0℃ and 1atm. Standard flow:  Conversion of measurement into a flow at the reference temperature and 1atm
*5 For communication specifications, see our company’s website to download it.
*6 High temperatures can cause the electronic circuit board to be deteriorated and the batteries to be consumed. To avoid unnecessary rise in temperature, the product is recommended to be fitted with a sunshade.
