Product Overview
RMB-50D is a series RM Rate-Master® polycarbonate flowmeter. It is a line of general use, direct reading precision flowmeters suitable for both gas and liquid applications. The Rate-Master® flowmeter bodies can be instantly interchanged, allowing the piping to remain undisturbed, interchangeability of the ranges and easy cleaning. Typical applications include medical equipment, air samplers, gas analysers, pollution monitors, chemical injectors and cabinet purging.
- 127mm scale, standard (no valve)
- Flowmeter range from 1.2-10SCFH and 0.6-5LPM air
- Temperature limit of 130°F (54°C)
- 1/4˝ female NPT connection
- Eliminate the need for troublesome conversions with direct reading scales
- Reduce installation damage and cost due to stainless steel backbone that absorbs piping torque
- Long operation life with durable, shatter-proof polycarbonate body
- High repeatability enabled by precision injection moulding around a precision tapered pin
- Increased reading accuracy with special integral flow guides that stabilize float movement
- Save time with instantaneous flow reading with the presence of scale graduations on indicating tube
