Nominal line size Drive mode frequency range and designation ULTRA-LOW (< 100 Hz) LOW (100 - 150 Hz) MID-RANGE (150 - 300 Hz) HIGH (> 300 Hz) 4 - 6 inch (DN100 - 150) N/A CMF350, CMF400 N/A N/A ≥ 6 inch (DN150) HC2, HC3, HC4 N/A N/A N/A Viscosity range For installations with 4 in (DN100) or larger meters, and fluid viscosities greater than 500 centistokes (cSt), consult your Emerson sales representative or technical support for guidance on optimizing your configuration. This recommendation is not applicable for smaller meters or processes with viscosities less than 500 cSt. Pressure relief ELITE sensors are available with a rupture disk installed on the case. Rupture disks vent process fluid from the sensor case in the unlikely event of a flow tube breach. Some users connect a pipeline to the rupture disk to help contain escaping process fluid. For more information about rupture disks, contact customer service. If the sensor has a rupture disk, keep it installed at all times as it would otherwise be necessary to re-purge the case. If the rupture disk is activated by a tube breach, the seal in the rupture disk will be broken, and the Coriolis meter should be removed from service. 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. Important If using a rupture disk, the housing can no longer assume a secondary containment function. NOTICE Removing the purge fitting, blind plug, or rupture disks compromises the Ex-i Safety Certification, the Ex-tc Safety Certification, and the IP-rating of the Coriolis meter. Any modification to the purge fitting, blind plug, or rupture disks must maintain a minimum of IP66/IP67 Ratings.
