Vortex shedding flowmetersThe Coolpoint vortex shedding flowmeters offer Intrinsic Safety as an option. CoolPoint vortex shedding flowmeters are electronic instruments that measure and monitor water flows. Unlike mechanical switches, the vortex shedding meters have no moving parts to stick or coat, eliminating potential for clogging by particles. The Intrinsic Safety feature is available on 1/4", 3/8", ½", 3/4", 1", 1 ½" and 2" CoolPoint meters. The transmitter with Intrinsic Safety is a 2 wire 4-20mA transmitter that has approved barriers and no display, alarm, or pulse output. It conforms to requirements for NEC Class I, Division 1, Group D environments.
The standard CoolPoint flow rate transmitter is a 4-20 mA 3 wire transmitter, which has the following standard feature and user-configurable options: Brass body with viton seals and PVDF sensors; available in pipe sizes ranging from 1/4 inch to 4 inches; flow repeatability is +/- .25 percent (1/4 of 1%); +/- 2% full-scale accuracy at maximum flow; turndown ratio 10:1; and 3 wire 4-20 mA flow rate transmitter with visual 3-digit LED readout, selectable alarm state (N.O. or N.C.), set point or pulse output and engineering unit choice of GPM or LPM.
