Technical Information RIA452 Panel meter Digital process meter in panel mounted housing for monitoring and displaying analog measured values with pump control and batch functions Application Water/wastewater sector Power industry Raw materials Chemicals industry Food industry 4 â Ó Your benefits 7-digit 14-segment LC display Multicolored Large bar graph with overrange and underrange Intrinsically safe input with transmitter power supply Digital status inputs for pump monitoring Universal input Up to eight relays Min/Max value saved Pump control functions Batch functions Flow measurement for open channels and weirs Linearization table with 32 support points Analog output Pulse output with totalizer Jog-shuttle operation Freely programmable units Configuration via interface and operating software ReadWin 2000 Tank linearization via ReadWin 2000 TI113R/09/en Function and system design Measuring principle Example of an application of the process display unit The single-channel process meter RIA452 monitors and displays analog measured values. Pumps can be monitored with the digital status inputs. The measured value is displayed using the seven-digit 14-segment LC display. Numbers and units are displayed in white, the bar graph in yellow, overrange and underrange in red and the limit value flags and digital status inputs in green and yellow. The RIA452 can provide power directly to two-wire transmitters connected. You have the option of selecting the input and the transmitter power supply as intrinsically safe for Ex applications. Up to eight freely programmable relays monitor the measured value for limit value overshoot and undershoot. Other operating modes for the relays include sensor or device malfunction, batch and pump control functions (e.g. alternating pump control). Furthermore, the RIA452 can be used as a preset counter and for measuring flow at open channels and measuring weirs. The scalable analog output offers many different ways of forwarding the input signal: zoom function, linearization, offset, inversion and signal conversion (input/output conversion). The optional pulse output gives the user the option of outputting integrated process values. Measuring system Microcontroller controlled meter in panel mounted housing with multicolored, illuminated LC display. The analog measured value acquisition takes place via an analog/digital converter. The digital status inputs are scanned cyclically. Power can be supplied directly to two-wire sensors with the transmitter power supply integrated as standard. The current input is optionally available as an intrinsically safe version for Ex applications. Here, the RIA452 has a second, intrinsically safe transmitter power supply. The freely scalable analog output is output via a digital/analog conversion. The digital pulse output is output directly. Up to eight relays are available in the device for monitoring limit values, pump control and batch functions. The device can be operated on site, using the jog/shuttle dial or via the PC with the ReadWin 2000 operating software. Operation can be locked using the hardware key or software code. 2 Endress+Hauser Linearization The following flow curves are stored for open channels and weirs: Khafagi-Vernturi channel ISO-Venturi channel BST 1) -Venturi channel Parshall channel Palmer-Bowlus channel Rectangular weir Rectangular weir with constriction NFX 2) rectangular weir NFX 2) rectangular weir with constriction Trapezoidal weir Triangular ( V ) weir BST 1) triangular weir NFX 2) triangular weir 1) BST: British Standard 2) NFX: French Standard NFX Flow formula can be freely configured The parameters α, β, γ and C can be entered freely. Linearization function Up to 32 freely definable support points are available in the device to linearize the input, e.g. for tank linearization. The linearization table for standard tanks and customer-specific tanks can be generated with the ReadWin 2000 operating software.
