Emerson's New Fisher® Level Products Give Design Options for OEMs and Contractors
No. 1 displacer level measurement brand in North America expands with Types DL3 and L3
MARSHALLTOWN, IOWA (February 9, 2004) - Emerson Process Management introduces two new wafer-bodied liquid level products that facilitate the design of processing or storage vessels. Designated the Fisher® Types DL3 and L3, these new wafer-style products allow direct, top mounting onto a vessel, or mounting between flanges of user-supplied fabricated cages. Available in 3 or 4-inch sizes, the wafer body fits Class 150 thru 600 raised-face flange connections. Automation users voted "Fisher" the number one brand of displacer level gauges as reported in the annual CONTROL Magazine Readers' Choice Awards.
To assist OEM and contractor vessel designers, Emerson provides guidelines to mount the Types DL3 and L3 to various liquid level cage configurations.
The Types DL3 and L3 are designed to sense the level of a liquid, the level of an interface between two liquids, or the density of a liquid in a vessel using displacer technology. The DL3 produces a 4-20mA analog output signal and is HART® compliant. The L3 produces a pneumatic output signal.
