Metering flow switches

Mountain View, Calif. —The 500 Series metering flow switch combines flow switching and metering in a single compact unit. Unlike thermal-sensing devices, the 500 Series is said to provide accurate measurement of flow over a wide temperature range. Flow response remains constant over 104 °F, providing users with improved control capability in critical process steps.

Mountain View, Calif. —The 500 Series metering flow switch combines flow switching and metering in a single compact unit. Unlike thermal-sensing devices, the 500 Series is said to provide accurate measurement of flow over a wide temperature range. Flow response remains constant over 104 °F, providing users with improved control capability in critical process steps. The flat temperature response of the device can be applied in the range of -140 to 284 °F. The flow sensors are formed in stainless steel and provide either NTP or SAE connections in two versions covering flows of 0.15- 2.0 gpm and 0.3- 4.5 gpm. Calibration of the 5 V dc output is controlled against traceable standards, providing flow measurement accuracy of www.proteusind.com Proteus Industries Inc.
