A five path ultrasonic and/or magnetic flowmeter were installed after valve. Five path ultrasonic flowmeter were tested to obtain it's performance in a water flow standard system and magnetic flowmeter. It's varied with straight pipe length(nD), install direction and valve position.<br/> All the results are summerized. The multi-path flowmeters(MUF) showed up to ±0.5% at a 2, 4, 8, 15D spacing : the MUF was significnatly better than magnetic flowmeter at disturbed flow conditions.
