Ultrasonic Gas Meters
Ultrasonics is used as the measurement principle. There is no obstacle inside the measurement tube so the pressure loss is zero and the energy loss is zero. The meter has a wide range ability of 1:400 which allows for correct measurement with low flow rates.
Aichi AS-WE ultrasonic gas flow meters 40mm to 200mm.
New Aichi UX range 15mm to 50mm.
Also available are Siargo Thermal Mass gas flowmeters and Esters oscillating gas meters .
