ST – VENTURI TUBES Venturi Tubes Venturi tubes are reliable, easy to use and maintenance-free flow meters. Venturi tubes are particularly well suited to the measurement of clean liquids and gases. Venturi tubes are preferred over other differential pressure flow meters as their design encourages a higher pressure recovery and reduced upstream and downstream pipe …
ST AT DIFFERENTIAL PRESSURE TRANSMITTER ST AT Differential Pressure Transmitter ST AT Advanced Transmitter is a microprocessor-based smart transmitter that features high performance and excellent stability. Capable of measuring gas, liquid, vapor, and liquid levels, it transmits 4 to 20 mA DC analog and digital signals according to the measured differential pressure. It can also …
ST – ORiFICE FLANGE UNIONS Orifice Flange Unions Orifice Flange Unions are available in a range of standard line sizes and configurations with optional materials available upon request. OFU’s used for flow measurement applications will have differential tappings added to the flanges. OFU’s used for Restriction or Spectacle Blind applications will not require tapping points. …
ST – PADDLE BLINDS AND SPACERS Paddle Blinds and Spacers Paddle Blinds and Spacers are used to assist with the isolation of sections of pipework from flowing or pressurized mediums, to enable safe maintenance. Paddle type blinds are of a single disc construction with a tab handle or ‘T’-bar handle that can be seen when …
ST – RAISED FACE PADDLE PLATES Raised Face Paddle Plates Raised Face Paddle Plates are used for flow metering or restriction applications, where the orifice plate is installed between ASME B16.36 flanges for flow metering applications or ASME B16.5 flanges for restriction applications. The assembled units are referred to as Orifice Flange Unions. DOWNLOAD DATASHEET …
ST500 Series Universal Orifice Plates ST500 Series ‘Universal’ Orifice Plates Universal orifice plates are used within orifice meters (see Roto-Boss™ brochure), some types of Orifice Flange Unions and also in Annular Chambers. They are termed as “universal” as they are manufactured to industry standard outer diameters and plate thicknesses to comply with measurement standards such …
ST – BLEED RINGS Bleed Ring Bleed Rings (also known as a “vent rings”, “flushing rings” or “drip rings”) provide a means for draining/venting of pipe streams, sample take off points, attaching instruments or even bleeding of valves. Bleed rings are fitted to standard flanges and are retained within the flange bolt circle using conventional …
ST – CONDENSATE POTS Condensate Pots The primary use of condensate pots is to increase the accuracy of flow measurement in steam pipelines. They provide an interface between the vapour and condensed phases of the fluid in the impulse lines. The condensate pots are available in a range of materials and sizes and are designed …
ST – CONDITIONING RTJ PADDLE PLATES Conditioning RTJ Paddle Plates Conditioning orifice plates are specially designed 4 hole orifice plates that condition and correct the flow profile at the point of measurement. They require only a 2D upstream and 2D downstream straight length and the use is intended for non-fiscal measurement applications. The design can …
ST – FIGURE 8 SPECTACLE BLINDS Figure-8 Spectacle Blinds Figure-8 spectacle blinds are used to assist with the isolation of sections of pipework from flowing or pressurized mediums, to enable safe maintenance. Figure-8 spectacle blinds are of a dual disc construction with a tab joining the blind and spacer rings. When the spacer disc is …
