Bel-Art Products 40402-0020 Riteflow Guarded Flowtube 65mm Size 4

Universal Millimeter Scales Ideal for flow measurements in the lab, in pilot plants, chromatography, and in manufacturing processes, these heavy-walled, shock-resistant flowmeters feature borosilicate glass construction. The height to which the float rises within the metering tube is correlated with specific flow rates on the Mm scales, through the use of appropriate calibration data sheets or curves. Flow measurements are taken by reading the center of the float on the Universal Scale. These units offer a minimum 10:1 useful flow range with one float; better than 20:1 useful flow range with two floats. Unmounted tubes have plain ends; guarded tubes are sheathed in a plastic housing. Panel/bench mounted flowmeters available with PTFE or aluminum valves. Scales of this type permit utilization of a given flowmeter for a diverse range of different fluids at diverse pressure and temperature conditions. Riteflow Guarded Flowtubes: Especially when used under high pressure, guarded tubes reduce risk and offer a greater margin of safety and protection against shattering flowtubes. The flowtube is shrouded in a plastic cylindrical guard which has two end bushings, 6.3mm (1/4") NPT fittings and an O.D. of 25mm (1"). Maximum operating pressure is 200 psig with a maximum operating temperature of 65.5°C (150°F). Operating pressures up to 200 psig and maximum temperatures of 121°C
