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 meas-urement of flow over a wide temperature range. Flow response remains constant over a range of 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 0.15 to 2.0 and 0.3 to 4.5 gpm. Calibration of the 5 V dc output is controlled against traceable standards, providing flow measurement accuracy of
