Planning Installation Manual April 2020 20002298 Table 2-3: Preferred sensor orientation Liquids Gases Slurries and self-draining applications □ Install the meter so that the flow direction arrow on the sensor case matches the actual forward flow of the process. (Flow direction is also software-selectable.) Best practices The following information can help you get the most from your sensor.
• Temperature limits may be further restricted by hazardous area approvals. Refer to the hazardous area approvals documentation shipped with the sensor or at www.emerson.com/flowmeasurement. • The extended-mount electronics option allows the sensor case to be insulated without covering the transmitter, core processor, or junction box, but does not affect temperature ratings.
Installation Manual Mounting 20002298 April 2020 Mounting Mount the sensor Use common practices to minimize torque and bending load on process connections. NOTICE • Lifting the sensor by the electronics or purge connections can damage the device. • To reduce the risk of collecting liquid in the electronics housing, do not orient transmitters or sensor junction boxes with their conduit openings pointing upward.
Mounting Installation Manual April 2020 20002298 NOTICE Keep the extender and feedthrough clean and dry. Moisture or debris in the extender or feedthrough can damage electronics and result in measurement error or flowmeter failure. Procedure 1. Remove and recycle the plastic cap from the feedthrough on the sensor. Figure 3-1: Feedthrough and extender components A.

Installation Manual Supplementary information 20002298 April 2020 Supplementary information Purge the sensor case Prerequisites Make sure the following are available before beginning the purge procedure: ™ • Teflon tape • Argon or nitrogen gas sufficient to purge the sensor case Whenever a purge plug is removed from the sensor case, you must purge the case again.
Supplementary information Installation Manual April 2020 20002298 • If the purge gas is heavier than air (such as argon), locate the inlet lower than the outlet, so that the purge gas will displace air from bottom to top. • If the purge gas is lighter than air (such as nitrogen), locate the inlet higher than the outlet, so that the purge gas will displace air from top to bottom.
Installation Manual Supplementary information 20002298 April 2020 WARNING • Orient the sensor so that personnel and equipment will not be exposed to any discharge along the pressure relief path. • Stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from the sensor can cause severe injury or death.
