FLOW METERS WITH FLOW METERS METALLIC TUBE RIV500 series metal tube flowmeters The flowmeters with Riels®Instruments index of this series are completely metallic instruments, having all parts in contact with the fluid in AISI 316L or PTFE. The position of the float is shown outside by magnetic coupling with the mobile crew, placed inside the indicator. The spacing of only 250 mm between flange and flange is a significant peculiarity of this series of small footprint tools. These flowmeters are suitable for installation on vertical pipelines with ascending flow and do not require straight sections of inlet and outlet pipelines. In addition to the basic version, they are available with microprocessor electronics and two wire technology, in the intrinsically safe version EEx i and in the explosion-proof version EEx d.
