22. MEASURING WITH EC PROBES
22.1. GENERAL INSTALLATION CONSIDERATIONS
• Probes are easily installed using the ¾” NPT external thread.
•
Hand tighten the probe in position. Then, depending on the process, tighten one or two turns with a wrench
to secure in place. Do not exceed the 10 N•m (7.3 lb‑ft) torque specification for the probe sensor.
• Consider probe accessibility for maintenance when selecting placement.
Note: See EC industrial probes manual (MAN7630-8) for series configuration options and detailed
specifications.
22.2. INSTALLATION SCHEMES & MOUNTING ACCESSORIES
Accessories are sold separately!
In‑line mounting and flow‑cell installation require that the saddle and flow cell are completely filled with water.
