Mass Flow ONLINE B.V., specialist in low flow measurement and control, presents new models of their LIQUI-VIEW Base se- ries. Following consultation with custom- ers, these models are now equipped with a bright, wide-angle and easy-to-read display for local readout purposes. As the working principle of the instrument allows it to be mounted in any position, the structural de- sign of the display makes it possible to ro- tate it through180 degrees. Besides a local readout, these models also offer 4-20 mA output signals. The LIQUI-VIEW Base series operates on the vortex principle. The obstruction (bluff body) placed in the flow of the liquid sheds vortices downstream at a frequency proportional to the velocity of the liquid. A piezoelectric sensor detects the vortices and creates electrical pulses which are pro-

portional to the liquid flow rate. The instru- ments can be mounted in any position and can be supplied in full scale ranges from 10 l/min up to 150 l/min at max. 12 bar pres- sure rating. LIQUI-VIEW Base instruments offer a cost-effective solution for monitoring the flow or consumption of cleaning water, cooling water or spa water. Thanks to its IP65 protection rating and the compact and lightweight sensor body, these flow meters will be the best choice for many industrial applications. The new LIQUI-VIEW Base can be or- dered easily from stock at Mass Flow ONLINE B.V. 24 hours a day, seven days a week on www.massflow-online.com.

Industrial Analogue temperature measurement

to a pointer element. A stainless steel immersion shaft protrudes into the medium at the other end. For applications with strong vibrations, the gauge measuring system may be dampened with glycerine or oil. The TNS is a stem thermometer according to DIN 16205. The TNF series comprises of capillary thermometers accord- ing to DIN 16206. Up to 100 m capillary between probe and housing enables a remote and reliable temperature monitor- ing. A variety of typical industrial connections and options allow mounting the instrument exactly as per specified re- quirement. The 16 standard measuring ranges range from -40°C to 600°C. Special measuring ranges are also available. The protection degree is IP65. Designs with one or two contacts enable a reliable monitoring of limit values. Slow-ac- tion contacts, magnetic spring contacts or inductive con- tacts are available to choose from. Instruments with induc- tive contacts together with an external switching amplifier are suitable for use in hazardous areas. Areas of application in the following industries: chemical, food, mechanical engi- neering and heavy goods, piping and vessel construction and process engineering.
