EVM430-FR6047: about ultrasonic water meter measuring rate

Hi Champs,

Our user's guide suggests measuring rate as once a second.

is this practical measuring rate that can be applied to mass production?

In real use case, should customer use higher measuring rate for more accurate result?

Regards,

Ted

    Hi Ted,

    This is the rate used in all of the testing and published accuracy results on the web.  

    In terms of accuracy, not necessarily.  But keep in mind that a higher measurement rate will increase the power consumption.  This is why many customers use this measurement rate. It's a trade-off between accuracy and power.
