Brooks Instrument 1355EEA6AEB1A Sho-Rate Flowmeter

The Brooks Instrument Sho-Rate 1355 series glass-tube flow meter, model 1355EEA6AEB1A, is a 150 mm tube variable-area flowmeter (rotameter) designed for direct, inline measurement of gas or liquid flow in lab and process environments. It uses a floating indicator in a transparent glass tube with a calibrated scale to display flow rate and can be ordered with or without integrated valves (No Valve, Standard Inlet Valve, Precision Inlet Valve, and corresponding outlet valves), depending on the exact ordering code. For the Sho-Rate 1350/1355 family, performance is typically up to 3% accuracy with about 0.25% repeatability, with the exact figures determined by the specific tube number and fluid being measured. Brooks recommends mounting the meter within 6 degrees of true vertical to ensure accurate readings, and note that ranges and units of measure vary by model and tube selection.
