ISO 12242:2012
Measurement of fluid flow in closed conduits -- Ultrasonic transit-time meters for liquid
Product Details
There are no limits on the minimum or maximum sizes of the meter.
ISO 12242:2012 specifies performance, calibration and output characteristics of ultrasonic meters (USMs) for liquid flow measurement and deals with installation conditions. It covers installation with and without a dedicated proving (calibration) system. It covers both in-line and clamp-on transducers (used in configurations in which the beam is non-refracted and in those in which it is refracted). Included are both meters incorporating meter bodies and meters with field-mounted transducers.
