Brooks Instrument Sho-Rate 1355E Glass-Tube Variable-Area Flow Meter
About this part
Brooks Instrument 1355EDA8CNE1A is a configured Sho-Rate 1355E variable-area flow meter with a 150 mm glass metering tube. Its DA8 tube-and-float code specifies an R-2-15-B borosilicate-glass tube, sapphire spherical float, and 0–150 mm scale. The legacy 1355E capacity table gives maximum reference capacities of 76.2 cm³/min water and 2.92 standard L/min air. Process fluid, calibrated direct-reading range, fittings, valve details, and elastomers should be confirmed from the unit label or manufacturer order record
Configurations vary. Verify the exact unit before choosing a replacement.

What Does 1355EDA8CNE1A Mean?
The model and tube-and-float portions can be decoded from Brooks 1355E literature. The remaining configured-option values require a readable ordering record or unit label before their individual meanings are asserted.

Interpretation
1355E
Base model
Brooks Sho-Rate “150” glass-tube variable-area flow meter with a nominal 150 mm scale.
DA8
Tube, float, and scale
R-2-15-B borosilicate-glass tube; sapphire spherical float; standard 0–150 mm scale. Legacy 1355E reference capacities are 76.2 cm³/min water and 2.92 standard L/min air.
C
Fitting/end-fitting option
Configured option C. Do not assert its construction or connection size without the manufacturer order record or readable unit label.
N
Valve or controller option
Configured option N. Do not assert the valve/controller type from the identifier alone without a reliably readable ordering table or unit label.
E
Packing and O-ring option
Configured seal option E. Do not assert a specific elastomer combination without the manufacturer order record or unit label.
1
Valve/controller location option
Configured location value 1. Exact inlet/outlet interpretation requires the manufacturer order record or unit label.
A
OEM identification option
Configured identification value A. Exact marking or customer-label treatment should be confirmed from the unit label.
Capacity Interpretation
The water and air figures are alternative reference capacities for the DA8 metering-tube and float combination, not simultaneous operating ranges and not proof of the configured process fluid. Brooks notes that direct-reading scales can terminate at slightly different maximum flows. Use the tube scale, calibration data, fluid, pressure, temperature, density, and viscosity information supplied with the individual meter for service decisions.
