1358F1C1EC2B1A is a configured Brooks Instrument Sho-Rate 1358 glass tube variable-area flowmeter. Official Brooks 1358 documentation identifies Model 1358 as a Sho-Rate Size 8 low-flow indicator for water flow rates up to 5.0 gpm depending on float selection; the configured code decodes as a 1358F base meter with tube code 1, 8-RJ-23 stainless-steel float, scale on tube, GPM liquid scale for specific gravity 1.0 and viscosity 1.0 cP, Viton packing/O-rings, 3/8 inch NPT 316 stainless fittings/adapters, stainless needle valve on the inlet, back/back port orientation, and no accessory code. Verify the physical scale and label before using the unit in service because calibrated flow range and process compatibility remain configuration- and condition-dependent
Configurations vary. Verify the exact unit before choosing a replacement.
