60 Flow Level Pressure New flow transmitter with digital signal processing


now part of restructured Coriolis product portfolio Sister companies AW-LAKE COMPANY and KEM Küppers Elektromechanik GmbH (KEM) announce the expansion of their TRICOR line of Coriolis Mass Flow Meters that now includes both standard and advanced flow meters and the addition of the TCD 9000 Series Transmitters that incorporate digital signal processing (DSP).


The TCD 9000 Series Transmitters offer higher flow and density capacity, a very rapid response, enhanced zero stability, higher immunity from the effects of process noise, improved gas void fraction and temperature stability, application adaptive filtering andsensor checking and troubleshooting wizards . The TCM “CLASSIC” Series meets general industrial requirements out of the box while the TCMP “PRO” Series offers environmentally-hardened units with advanced performance specifications and diagnostic capabilities for operation in challenging environments.


TCM CLASSIC Series, used for challenging liquid fluid conditions, include some great new features such as their TCE 8000 transmitters with their easy-to-use interface, the economically-priced, standard calibration and optional custom-calibrated meters with high performance specifications. The TCMP PRO Series includes the TCD 9000 transmitters with digital signal processing and advanced diagnostics, strong logging and traceability functions, flexible I/O configurations 1-4 channels fully configurable with programmable IO options and its ability to report fraction concentrations of two-part mixtures.


The new TCD 9000 Series of transmitters offers greater robustness, performance, diagnostics, and connectivity options. With a modern HMI interface and a strong logging functionality, the DSP transmitters provide users with an efficient configuration and analysis tool.


Operating from one universal power supply (24 V to 240 V), the TCD 9000 Series Flow Transmitters feature a large graphical display, SD card connectivity as well as logging and traceability functions. Units are available with direct or remote mounts and Profibus PA, Profibus DP, Modbus, or HART communication protocols. The transmitter is also available with Modbus only communication without display.


flow transmitters feature a SD card to access internal storage information such as configuration details, calibration protocols and manuals. Operators can also access log data and configure operating parameters via the SD card and change TCD firmware in the field. TCD 9000 Series Transmitters are designed for numerous product certifications and developed for hazardous areas.

Testing pressure safety valves just got a lot easier


In the past it was difficult to test Pressure Safety Valves (PSVs) because a digital gauge, a steam or gas source and a clipboard were needed. After the test was done all the data was recorded, passing valves were measured and all data was recorded by hand. This information was then transcribed into a computer for use in generating a certificate. Not any more.


Now with the Ralston Instruments PSV Test suite of software and hardware it is possible to conduct the test and record most of the information on the calibrator. After the test is completed the data is then transfered electronically to a PC where a certificate with graphs, customer data, tag data and other required information can be created.


The unique PSV test mode captures the PSV crack and reseat pressure by logging pressure at 128 times per second. Most competitors’ devices do not reliably capture the crack and reseat because the logging rate is too slow. The PSV mode also allows the user to select from standards such as ASME Boiler Code


Section 8, simple crack tests or conditional crack tests where the allowable error may depend on the pressure of the PSV. the user can enter the pressure of the valve at the time of test and type in any other important information right on the FieldLab. Thus when the user returns to the office they can download all important information and create the certificates without a lot of extra effort.


The PSV test mode works with steam and gas valves as well as liquid valves where the user needs to witness the first steady stream of liquid prior to recording the crack pressure. It also has the option of running a leak test and logging the change in pressure and whether any leakage was observed. This provides a great deal of flexibility and allows for a smoother and more reliable workflow in conducting PSV tests. The FieldLab is available from 200 kPa to 70 MPa so it covers the ranges of most PSVs in the field. It is also rated IECEx rated Ex ia IIC T4 Ga (-10 < Ta < 50 °C)so that it can be used in most hazardous locations without a problem.

Versatile FLT93 Stainless Steel Switch Toughs It Out In Marine, Corrosive and Heavy Wash- Down Applications


With its no-moving parts flow/level sensor housed in a stainless steel package and NEMA 4X enclosure, the robust SIL-2 rated FLT93 Series Switchfrom Fluid Components International (FCI) is ready for the most punishing heavy marine seawater, acidic or alkaline fluids and wash-down cycles encountered in a wide range of industrial processes and plant environments.


The field-proven FLT93 Switches provide air/gas flow or point level measurement wherever exposure to seawater, salty air, harsh process fluids and heavy wash-downs are a requirement. Its flow/level sensors come in stainless steel, Hastelloy or other exotic metals for demanding service environments. This versatile switch offers users a choice of insertion or inline mounting, faster response or high flow rate capabilities and optional sanitary service.


Testing Pressure Safety Valves just got a lot easier


• Create PSV test certificates with all test and traceability information and graphs of each test


• ASME boiler code standard tests are built-in options


• High-speed data logging of PSV crack and reseat pressures (128 times/second)


• Manually mark observed Proportional Relief Valve crack and reseat pressures


• Record tag, valve and customer information or other important information in the field


• Works with steam, gas or liquid pressure sources


• Optional leak test will run a leak test and log pressure drop and lets user confirm whether there is leakage


• FieldLab hardware is Intrinsically Safe (Class 1, Div 1) and ATEX, IECEx approved for Zone 1


• Free FieldLab Desktop software to configure tests and download and export test results is included


The FLT93 Switch is a dual-function instrument that indicates both flow and temperature, and/or level sensing in a single device. Dual 6A relay outputs are standard and are assignable to flow, level or temperature. Based on FCI’s thermal dispersion expertise, the unique sensor technology of the FLT93 Switches, combined with FlexSwitch™ temperature-compensation circuitry, introduces unparalleled performance capabilities:


Exclusive flow accuracy as precise as ± 2% of the setpoint velocity over ±50°F [± 28°C] temperature range; repeatability of ±0.5% reading


Level resolution of ± 0.1 inch [± 2.5mm]; repeatability of ± 0.05 inch [± 1.3mm]


Standard temperature accuracy ± 2.0°F [± 1°C]; repeatability ± 1.0°F [± 0.6°C]; improved temperature accuracy is available with factory calibration.


One standardised, field-configurable FLT93 FlexSwitch control circuit satisfies virtually any combination of application requirements. FCI’s advanced FlexSwitch technology can be packaged in integral or remote configurations for installation flexibility.
