Advanced liquid level transmitter for sanitary tank gauging

Jon Lawson

MTS Sensors has further extended its recently announced LP-Series of liquid level transmitters by introducing the Level Plus SoClean level transmitter. Based on the company’s proprietary Temposonics magnetostrictive technology, these accurate and robust devices are targeted specifically at sanitary tank applications within the pharmaceutical and food/beverage industries - such as bottle filling, blending tanks, bioreactors, buffer mix tanks, etc. Their innovative 3-IN-1 measurement function allows product level, interface level and an average product temperature to all be simultaneously determined. They have a ±1mm inherent position accuracy and a ±0.1°C temperature accuracy.

SoClean liquid level transmitters are fitted with 15.9mm (5/8 in.) outer diameter (OD) rigid pipe. Four different mechanical end plugs are available to fit with individual customer needs, with a minimum measurement length down to 305 mm (12 in.) and a maximum measurement length reaching 7620 mm (300 in.) supported. NEC, CEC, ATEX, and IECEx approvals have been received for the Intrinsically Safe protection method. Each device features an integral display to maximize user convenience.

MTS liquid level transmitters are suitable for cleaning via steamed-in-place (SIP) or cleaned-in-place (CIP) processes. They are offered with Stainless Steel and Electropolished Stainless Steel wetted parts. Once they have been installed and calibrated, these devices do not require any scheduled maintenance or recalibration work. This presents customers with a ‘set it and forget it’ solution that minimises running costs.
