The ISM 5.0 insertion magmeter from Greyline Instruments measures the flow of conductive liquids in full pipes. It installs through a tap in the pipe wall and is designed for 3- to 72-inch-diameter lines. Installation through a full port ball valve allows for easy retraction and reinsertion without shutting down flow. The magmeter has no moving parts. Features include a dual-electrode sensor and continuous auto-zero function, selectable 4-20mA, 0-5 volt or 0-10 volt output. Other features include 0-500 Hz frequency output and scalable pulse output. 888/473-9546; www.greyline.com.
