MR3A03SVVT

Brooks MR3000 1–11 SCFH Air Variable-Area Flowmeter

About this part

Brooks MR3A03SVVT is an MR3000 Series mechanical variable-area purgemeter with a direct-reading 1–11 SCFH air scale. Its ordering code specifies stainless-steel fittings, a standard inlet control valve, and Viton fluoroelastomer seals. The meter has 1/8-inch FNPT inlet and outlet connections and is rated for ±4% full-scale accuracy, 100 psig maximum pressure, and 150°F (65°C) maximum temperature

Configurations vary. Verify the exact unit before choosing a replacement.

What Does MR3A03SVVT Mean?

The published MR3000 ordering structure decodes the complete identifier without normalization.

Segment	Field	Interpretation
MR	Base model	MR3000 molded-polycarbonate flowmeter body and tube
3A03	Tube code	Direct-reading 1–11 SCFH air scale
S	Fittings	Stainless-steel fittings
V	Valve	Standard valve configuration; the separately defined O code denotes an outlet valve, establishing V as the standard inlet-valve arrangement
VT	Seals	Viton fluoroelastomer seals for the stainless-steel configuration

Operating and Service Notes

Mount the meter vertically and minimize vibration and internal flow variation.
Read a ball float at its center or a bullet float at its indicating groove; the exact float type is not defined by this identifier.
Do not exceed 100 psig or 150°F (65°C), and do not use the meter with hazardous fluids.
Consult chemical-compatibility data before using a fluid other than air or water.
Clean removable wetted components with clean water and a soft brush. Do not use solvents or strong bases.

Details Not Defined by the Model Code

Exact float materialNot encoded in the published identifier. Family choices include black glass, carbide, stainless steel, and aluminum; unit-label or calibration evidence is required for an exact claim.

Unit-specific calibrationNo individual calibration certificate or reference-condition record was identified. Do not assert unit-specific calibration details beyond the documented scale and family accuracy.
