Vortex shedding CalPoint measures temperature and transmits readings to process controller. Repeatability is ±1% of actual flow and ±0.25% of actual temperature. In chiller applications, meter verifies that flow and temperature from return branches are balanced. Device is offered in pipe sizes from 3/4-2 in.; measures flow rates from 2.5-200 gpm; and operates over 32-210°F.
