39E Solid-State Flow Sensors User Manual Installation instructions 1 Vm L Figure 3 Installing Bulletin 839E (example). Sensor length L is completely immersed in the flow profile. Mounting instructions: • • • • • • • Any orientation The on-site display can be rotated electronically 180° — see “Operation” section. The housing can be rotated up to 310° for optimal readability and ease of wiring. Minimum sensor immersion length: L ≥ 10 mm (0.4 in.) The sensor tip should not touch the pipe wall.
839E Solid-State Flow Sensors User Manual Installation instructions Installation conditions Note! The sensor requires a fully developed flow profile for correct monitoring. For this reason, steadying sections (5x DN) must be provided in the pipe after a pump, pipe bend, internal fittings and cross-sectional changes. ATTENTION Do not turn the device into the process connection thread at the housing. Always install the device at the spanner flats (Figure 4, item 1).
839E Solid-State Flow Sensors User Manual Wiring • The sensor tip should be completely surrounded by medium. • Position the sensor tip in the area of maximum fluid velocity (pipe center). • Minimum sensor immersion length: L1 ±10 mm. Figure 4 Installation conditions Orientation: • For horizontal pipes: lateral installation. Note! Installation from above (see Figure 4) only if the pipe is completely filled with medium during operation. • For vertical pipes: installation in the ascending pipeline.
