Dwyer Instruments DR4204 | High Flow glass Flowmeter | Flow rate 1-16 SCFM (20-500 SLPM) air
Glass flowmeters of the DR4204 model provide a more straightforward approach to the fluid flow indication issue at larger capacity levels. Flowmeters are made to endure even the most demanding industrial applications and have a straight reading scale for either water or air. For the best float performance, a permanently fused ceramic scale features integrated float guides. More precise readings are possible thanks to the 1.5 X magnification lens and reflective plastic backdrop, which also lessen eye strain. For added security, units have a safety blow-out rear panel.

- Simplifies fluid flow indicator by offering a straight reading scale for air or water, particularly at greater capacity levels.
- Designed to endure the most demanding industrial applications, guaranteeing durability and dependability in difficult settings.
- Because the ceramic scale is permanently bonded, it is more durable and consistently provides precise readings.
- Has built-in float guides for optimal float performance and accurate measurement.
- makes use of a reflective plastic backdrop and a 1.5x magnification lens to provide more precise readings while minimizing eye strain.
- Has a safety blow-out rear panel to provide extra security and guarantee safety in the event of an emergency or pressure buildup.
