Ultrasonic Flow Meter for Propane/Butane/Coal Gas and Fuel Gas

Ultrasonic flow meters measure the difference of the transit time of ultrasonic pulses propagating with and against flow direction. This time difference is a measure for the average velocity of the fluid along the path of the ultrasonic beam. By using the absolute transit times both the averaged fluid velocity and the speed of sound can be calculated.It realizes a wide range of measuring ability that includes microflows using the characteristics of ultrasonic waves. It is resistant to dust so there is no need to install filters. The flow meters are perfect for low flow gas measurement such as food and controlling gas usage of small-scale furnaces.

  • You have a choice of driving power supply.Select from AC power, DC power and built-in batteries.External power supply 24VDC| 110VAC and in-built lithium battery.
  • Measurable gases: Propane, Butane, Town gas and fuel gas
  • Battery life is five years (under an average environment temperature of 20°C). The batteries can be replaced on-site.
  • High performance that supports a wide range of flow rate.Realizes a wide range of 1:50, covering minimum to maximum flow rates.
  • Dust resistant and highly durable.No need to install filters.
  • Space-saving, as it requires no straight piping.Measures with a high degree of accuracy even installed immediately after elbow piping.
  • A variety of output functions support visualizing flows. Unit pulse/ 4 – 20 mA DC/ RS485 (Modbus/RTU)* RS485 is only for the AC or DC power models.
