Specifications of Ultrasonic Flow Meter UX/UZ for Fuel Gas Management Model Maximum working pressure Gas type ※1 City gas (13A), butane (butane = 70%, propane = 30%), propane (propane = 98%, butane 2%), nitrogen and argon Battery ※2 Power/ AC power consumption DC power Flow range City gas, nitrogen and argon (Actual flow) Butane and propane Ultrasonic Flowmeter Temperature and pressure compensation ※4 Conversion accuracy ±4%RD (for a range of 10% to 100% of the max flow) ±0.5%FS (for a range of 2% to 10% of the max flow) Pipe connection Yes/No (Normal/Standard conversion) ±1.5%RD(@23℃ and 100kPa) Developed jointly by Tokyo Gas Co., Ltd. and our company Accumulated flow (actual flow: 8-digit integer + 2 decimal places, converted flow: 8-digit integer + one decimal place, accumulated flow of trip function) Main display Alarm indication (for ultrasonic sensor, temperature sensor, pressure sensor, external memory and power voltage (for battery operation only)) (For 100VAC or 24VDC only) 4-20mADC (load resistance = max 400Ω): choose among options of instantaneous flow, temperature and pressure (default = instantaneous flow) Output 1 (accumulated flow volume pulse): standard = 1000L/P (choose 10, 100, 1000 or 10000 L/P): duty = 20 ‒ 80% Instantaneous flow: 5 digits; temperature: 3 digits; and pressure: 5 digits Nch open-drain output (maximum load 24VDC, 50mA) Output 2 (alarms): upper & lower limits, or upper limits of accumulated flow (for 100VAC or 24VDC drive); low voltage, or upper & lower limits (for battery drive) Fluid temperatur Ambient working temperature and humidity Protective structure Mass -10℃ to +60℃, under unfrozen condition -10℃ to +60℃, max 90%RH, no condensation permissible Indoor and outdoor use *6, IP64 (JIS C 0920) About 6.3kg *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 naccurate measurements. For other conditions for installation, please contact us. *4 Normal flow: Conversion of measurement into a flow at 0℃ and1atm. Standard flow = conversion of measurement into a flow at the reference temperature and 1 atom *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.

Needl Customer wants to install a flow meter immediately after a bend part in the piping Need3 Customer wants to replace batteries 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. Easy to replace batteries You can choose one of the three power supply options: The flow meter has to be located 10D or more distant from a governor irrespective whether it is placed upstream or downstream of the governor. Falling to meet this condition may lead to inaccurate measurements. (D = pipe diameter) Users...
