RM
Polycarbonate body variable area direct-reading flowmeters for general service gas and liquid applications. Choice of 2", 5", or 10" scale. Accuracy: 2% to 4% full scale, depending on scale height. For use in temperatures to 130° F and pressures to 100 PSI. Air/gas ranges available in SCFH, SCFM, cc/min, and LPM. Water/liquid ranges available in GPM, GPH, LPM, and cc/min.
- For air, water, and compatible gases and liquids. Not for use with caustic solutions, anti-freeze (ethylene glycol) or aromatic solvents
- Direct-reading scales eliminate the need for troublesome conversions
- Instantaneous flow reading from scale graduations on both sides of the indicating tube save time
- Stainless steel backbone that absorbs piping torque helps reduce installation damage and cost
- Durable, shatter-proof polycarbonate body for long operation life
- Increased reading accuracy with special integral flow guides that stabilize float movement
- Typical applications include air samplers, gas analyzers, pollution monitors, chemical injectors, cabinet purging, and medical equipment.
- Models shown here have stainless steel precision metering valves (-SSV). Call Lesman for other available options, including top-mounted valves, adjustable pointer flags, and NIST calibration certificates.
