The RIA15 loop-powered process indicator from Endress+Hauser is equipped with 4...20 mA or with HART® protocol. In the HART® version, up to 4 measured values of one sensor can be displayed alternately on the display. For this purpose the indicator can be set as Primary or Secondary HART® Master and actively query the values. The low voltage drop of < 1 V (< 1.9 V for HART®) proves to be a great advantage in Ex applications where only a limited voltage is usually available.

The conversation was highly helpful to me. I want to know about the suitable sensors that can be used for level measurements for conical tank systems. Mr. Pedro has quickly responded and explained in very ease way. It was nice interacting with him.
