Krohne introduces new flowmeter for use in milk reception with entrained gas

Krohne, a global manufacturer and supplier of solutions in industrial process instrumentation, has introduced an application of its OPTIMASS 1400 C Coriolis mass flowmeter for use in milk reception with entrained gas. One example of this application is the installation at the Chile-based milk dairy Surlat. This application can also be found in every similar facility around the world where trucks deliver fresh raw milk from local sources. The meter reduces time and costs required for unloading aerated milk from road tankers and provides continuous and reliable flow measurement, eliminating unplanned shutdowns caused by equipment failure.

Made of stainless steel and with hygienic Tri-Clamp connections, the Krohne twin straight tube (DN50) Coriolis OPTIMASS 1400 C mass flowmeter helps the dairy processing plant accurately measure milk quantities at the raw milk reception. Featuring Entrained Gas Management (EGM), the OPTIMASS 1400 C provides reliable readings even in the event of gas entrainment in the foamy raw milk. Foam produced due to movement and vibration of large road tankers delivering milk had caused other meters to completely stop measuring – interrupting unloading and even causing commercial disputes over the quantity of milk delivered.

The meter enables continuous and uninterrupted measurement of volume flow and mass, density, and temperature – even at difficult milk reception process conditions with 2-phase flow. Maintaining operation over a wide range of gas fractions and complex flow conditions, the OPTIMASS 1400 C is certified for hygienic use. Available from DN15…100 / ½…4-inches, and with a maximum of PN100/ASME Cl 600, it comes with many hygienic fittings. It features 3 x 4…20 mA, HART7, FF, Profibus-PA/DP, Modbus, PROFINET, and Bluetooth.
