Catalog excerpts

FLOWMETERS FOR SMALL FLOW FLOW CONTROLS Flowmeters for small flow-rates Flowmeters Riels® "L" are all-metal flow indicators for the measurement of gas or liquid flow-rates at high pressure and temperature with magnetic coupling for external reading. Besides the standard version, indicator flow meter it is available also electronic microprocessor transmitter - two wire technology - for safe areas (EEx i execution) on request. This model flow regulator; needle valve and minimum and maximum flow rate alarm switches. No gaskets. Flanged or screwed connections (top/bottom or elbow). Construction materials - Metering tube: AISI 3I6L stainless steel (other materials on request) - Float: AISI 3I6L stainless steel (other materials on request) - Housing: die cast aluminium epoxy paint finish (RAL 7001).
