These transmitters have no moving parts to stick, coat or bind. They are offered in pipe sizes 3/8 through 2 inches and flow rates from 6 to 200 gpm with a 10-1 turndown ratio. Electronic output is 4-20mA. Optional intrinsically safe circuitry is available to be used with an approved barrier in all hazardous location classes, divisions and groups. Accuracy is plus 2 percent of full scale and repeatability is plus 0.25 percent of indicated flow. 888/569-3090; www.flowmeters.com.
