Introduction


Series 1250/55 are flowmeters for liquids and gases available in 65 or 150mm scale lengths. These flowmeters can be configured with a standard or precision control valve on the inlet or no valve; fittings can be specified in either aluminum or stainless steel; valves can be specified in either brass or stainless steel; O-rings and seals can be provided in Buna-N, Viton® fluoroelastomer or other optional elastomers.

Sho-Rate™ 1250 / 1255 features include:

* Two accuracy levels: 5% Full Scale (Model 1250), 10% Full Scale (Model 1255)

* Standard direct-read scales for common units and fluids – 65 mm, 150 mm scale lengths (approximate)

* Inlet valve and outlet valve with options of cartridge valve, precision control valve or no valve

* Easy-change design allows quick interchangeability of tube assemblies

* Rotating lens provides a 180° view with magnification

Benefits

* Options offer value-added features to meet project or OEM requirements

* Borosilicate glass is resistant to thermal shock and corrosive gases and fluids

* Corrosion-resistant material options for scales, floats, fittings and valves accommodate demanding applications

* Integral float stops prevent loss of float during tube removal

* Enhance accuracy with easy-to-read scales with magnification

Applications

* Pharmaceutical production

* Research

* Chemical manufacturing

* Analytical instrumentation

* Water treatment and distribution systems
