Metering functions stated in the source

• Industrial gas flow meters
• Gas meters
• Gas velocity measurement
• Transit-time gas measurement modules

Matching the acoustic path and electronics
The acoustic path should be selected within the 0.15 to 2 m reference range while considering the 9.8° half-power beam angle, the operating gas and the available mounting geometry. The electronic interface should be matched to the 350 Ω ±20% minimum impedance and the 900 pF ±20% capacitance measured at 1 kHz. Peak voltage must be kept below 450 Vpp.

Environmental and configuration checks
Confirm operation within -40 to +80°C and at no more than 16 kgf or 1.6 MPa. The transducer is rated IP68. The stated 10.5 g ±5% weight applies to the version with a 22 cm cable, while exact mounting dimensions should be taken from the product drawing.
