The Sho-Rate 1350 and 1355 Series of low flow indicators provides a cost-effective means of flow indication for both 5% (Model 1355) and 10% (Model 1350) accuracy requirements. Available options include the Standard or NRS integral needle control valves, as well as flow controllers on the inlet or outlet of single tube meters. Multi-tube configurations with or without needle control valves, with individual connections or with manifolding of the inlet or outlet ports are also available.
Heavy-wall, precision bore, borosilicate glass metering tubes
A wide range of scales on the metering tube with contrasting background for easy readability
Tubes sealed on compression gasket by threaded seal spindle
Tubes removable without disconnecting instrument
Integral float stops prevent loss of float during tube removal
Interchangeable tubes and floats
Single tube or multi-tube configurations available
These Sho-Rate flowmeters are Variable Area, Glass Tube, flow rate indicating meters for both gas and liquid service. The basic elements are a tapered glass metering tube and a metering float. Features include quick and simple removal or installation of the tube and float while the meter remains in the process piping.
