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 – 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 …
ST – FLAT FACE PADDLE PLATES Flat Face Paddle Plates Flat Face Paddle Plates are flow metering orifice platesthat fit between orifice flanges by utilizing the PCD ofthe flange, ensuring concentric alignment. The orificeplate has the same hole diameter and outer diameter ofthe flanges. FF Paddle Plates are available in metric andimperial thicknesses. DOWNLOAD DATASHEET …
ST – Grounding rings Grounding Rings Grounding rings are used to suppress electrical interference at the installation location for electromagnetic flow meters (MAG meters). They are provided in pairs and are installed upstream and downstream of the flow meter. Sur-Tech grounding rings are flat paddle plate type wafer style rings designed to be installed between …
ST – MULTI HOLE UNIVERSAL ORIFICE PLATES Multi Hole Universal OrificePlates Multi Hole Universal orifice plates are intended for use in non-fiscal measurement applications. They can be 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 …
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. …
