Brooks Instrument Sho-Rate 1358 High-Flow Glass Tube Flowmeter

Name: Brooks Sho-Rate 1358 Glass Tube Flowmeter
Brand: Brooks Instrument
SKU: Sho-Rate 1358

Description

A simple glass tube flow indicator for 0.8 to 5.0 gpm of water

The Sho-Rate 1358 is a Brooks Instrument glass tube variable area flowmeter (rotameter) described in the datasheet as a cost-effective means of flow indication where accuracy requirements are not severe. It is the larger size 8 body in the Sho-Rate family and is stated to be ideal for flow rates from 0.8 to 5.0 gpm of water. Standard accuracy is 10 percent of full scale, with repeatability of 0.5 percent of full scale and a rangeability of 10 to 1.

The metering tube is heavy-wall, precision-bore borosilicate glass with interchangeable tubes and floats, and integral float stops prevent loss of the float during tube removal. The meter drops easily into a panel, and an integral needle control valve is available, as is a configuration to connect a flow controller at the inlet or outlet.

End fittings	Chrome-plated brass or 316 stainless steel
Connections	Standard horizontal female 3/8 inch NPT adaptors; other options by model code
Scale	Direct read on tube in gpm of water or scfm of air; optional special decal or detachable metal scale
PED status	Sound engineering practice (SEP) per Directive 97/23/EC

Selecting the Sho-Rate 1358 configuration

The sample model code in the datasheet reads 1358F 1 C 2 D C 2 B 1 A. After the base code 1358F, the code selects the tube (standard, CRN option or no tube), one of five stainless steel floats, the scale type, scale inscription (none, millimetre, SCFM air, GPM liquid at specific gravity 1.0 and 1.0 cP, or special inscriptions), tube packing and O-ring material, fitting and adapter material with 3/8 inch NPT connection (brass or 316 stainless, with or without locknut), valve configuration, and port orientation. Valve choices are none, a stainless steel or brass needle valve on inlet or outlet, or an adaptation to mount an 8810, 8910 or 8830 flow controller, which must be a second line item on the order.

What to confirm before ordering

Please send the fluid and its density and viscosity, the flow range and unit, pressure and temperature, the connection and port orientation, whether a valve or flow controller is needed and whether CRN is required. The meter is a low-accuracy indicator, so for tighter measurement the Sho-Rate 1355G or a metal-tube meter should be compared. The datasheet is short, and this page therefore carries only what it states.

About brand

Brooks Instrument makes mass flow controllers, flowmeters and pressure and vacuum instruments for gases and liquids. The industrial chemist Stephen A. Brooks started the business in 1946 as the Brooks Rotameter Company near Philadelphia, building variable area flowmeters. After many years as part of Emerson, Brooks was sold to American Industrial Partners at the end of 2007 and has been a division of Illinois Tool Works (ITW) since January 2012. It is headquartered in Hatfield, Pennsylvania.

Seven Star LLC is an independent supplier listing Brooks Instrument thermal and Coriolis mass flow controllers and variable area flowmeters for buyers in Oman and the GCC. Instruments are matched from the model code and the gas, range and calibration data on the label.

Where Brooks instruments are used

Brooks mass flow controllers dose gases in analyser systems, catalyst and pilot plant testing, gas blending, burner and combustion control, fuel cell test stands and semiconductor tools. Variable area flowmeters are widely used on purge gas, seal flush, sample and chemical injection lines in oil and gas, refining and petrochemical plants, where a simple local indication without external power is preferred.

Ordering Brooks instruments: what we need

Send the full model code and serial number from the label. Mass flow controllers are calibrated for a specific gas and full-scale flow, so state the gas or gas mixture, flow range, inlet and outlet pressure, temperature, process connection, seal material, signal (analog, RS-485, DeviceNet, EtherNet/IP or other) and any hazardous-area requirement. For variable area meters add the fluid, density, viscosity, flow range, connection size, materials and whether alarms or a 4-20 mA output are needed.
