Brooks Instrument SLAMF Series Digital Mass Flow Controller
About this part
SLAMF51S1BAB1K2A3 is a configured Brooks Instrument SLAMF Series elastomer-sealed digital thermal gas mass flow controller. The SLAMF model-code table supports the SLAMF51 body-size family and several hardware options in this suffix, but exact calibrated gas and full-scale range must be verified from the unit nameplate or calibration record. Stored auction evidence identifies examples as hydrogen service, but that auction context is not used as a model-wide specification
Configurations vary. Verify the exact unit before choosing a replacement.

Series family
SLAMF Series elastomer-sealed digital gas mass flow controllers and meters
Decoded base model
SLAMF51, interpreted from SLA + MF + function code 5 + body size 1
Function
Function code
5 = mass flow controller
Flow
Body-size flow class
Body size 1 is published for 15 to 150 lpm N2-equivalent full-scale flow class; exact configured gas and full-scale setting remain nameplate/calibration-dependent
Controls
Digital I/O communication code
S = RS485 with applicable analog I/O selection
Connections
Mechanical connection code
1B = 1/4 inch tube compression
Materials
O-ring material code
A = Viton
Valve
Valve seat and valve type codes
B = Viton valve seat; 1 = normally closed valve
Electrical
Analog I/O and power codes
K = 4-20 mA input and 4-20 mA output with 1/2 inch NPT(F) conduit; 2 = 24 Vdc power
Configuration
Output enhancement and certification codes

Applications
Application domain
Gas flow measurement and control for harsh, washdown, hazardous-area, laboratory, analytical, fuel-cell, biotechnology, life-science, chemical, and petrochemical process applications
Observed variants
Stored auction gas context
Stored exact-part auction titles describe hydrogen service; treat this as observed listing context, not an official calibrated gas/range specification
