Page 20: Mount The Transmitter
The following restrictions and recommendations apply to impulse piping location: Procedure 1. Impulse piping that runs horizontally must slope at least 1 in/ft. (83 mm/m). • Slope downward (toward the transmitter) for liquid and steam applications. Emerson.com/Rosemount... - Page 21 July 2024 Quick Start Guide • Slope upward (toward the transmitter) for gas applications. 2. Outdoor installations for liquid, saturated gas, or steam may require insulation and heat tracing to prevent freezing. 3. An instrument manifold is recommended for all installations. Manifolds allow an operator to equalize the pressures prior to zeroing and isolates the process fluid from the transmitter.
