Dwyer Instruments RMB-57 | Flowmeter | Range 60-600 SCFH air
A range of general-purpose, direct-reading precision flowmeters appropriate for both gas and liquid applications is represented by the Model RMB-57 Rate-Master® Flowmeters. These scales, which come in three different sizes—2" (51 mm), 5" (127 mm), and 10" (254 mm)—can be surface or panel mounted and come with an optional precise metering valve. The Rate-Master® flowmeter bodies may be quickly switched out within a certain Series, providing easy cleaning, interchangeability of the ranges, and uninterrupted pipework.Rate-Master® flowmeter bodies may be quickly switched out within the same series scale size, which facilitates range interchangeability, fast cleaning, and uninterrupted pipework.

- Direct reading scales remove the need for difficult conversions.
- Because the stainless steel backbone absorbs pipe torque, installation damage and costs are reduced.
- Long operational life and a sturdy, non-breakable polycarbonate body.
- Precision injection molding around a precisely tapered pin allows for high reproducibility.
- Improved precision of reading because to unique integrated flow guides that control float movement.
- With the ability to read flow instantly from scale graduations on both sides of the indicating tube, you can save time.
