l 4-Electrode Conductivity:The 1056 is compatible with Rosemount 4-electrode Model 410VP in the PUR-SENSE family of conductivity sensors. This sensor supportsa wide array of applications and is capable of measuringa large range of conductivity with one geometricconfiguration. Wired to the 1056, this sensor canmeasure 2µS/cm to 300mS/cm with an accuracy of 4%of reading throughout the entire range.l 4-20mA Current Input: Accepts any analog currentinput from an external device for temperature compensation of measurements and atmospheric pressureinput for partial pressure correction of oxygen. l Selective Ions: The analyzer is able to measureammonia and fluoride using commercially availableion-selective electrodes. All analyzers with installed pHboards can be programmed to measure selective ions. l Inferential pH: The analyzer is able to derive anddisplay inferred pH (pHCalc) using two contacting conductivity signal boards and the appropriate contactingconductivity sensors. This method will calculate thepH of condensate and boiler water from conductivityand cation conductivity measurements. l Differential Conductivity: Dual input conductivityconfigurations can measure differential conductivity.The analyzer can be programmed to display dualconductivity as ratio, % rejection, or % passage. 

8.unlike the direct spring operated PRV, the main valve will only open to a lift needed to flow the required capacity. Recall in figure 4-7 or 4-12, there is an abrupt lift (but not a full lift) at set pressure for gases or a gush of liquid during the overpressure of a direct acting relief valve. If there is any capacitance in the inlet piping to the valve, these direct acting devices may initially flow more than the source of overpressure can provide. The modulating action pilot operated PRV operation will conserve the product during an upset, minimize interaction with control valves trying to balance the system, lower reaction forces in the piping supporting the PRV, reduce noise levels and provide stability at low required capacity relieving contingencies. API Standard 521 and ISO 23251 will allow piping that is immediately downstream of a modulating PRV to be sized based upon the required capacity rather than the rated capacity. This can optimize the pipe size and save installation costs.The blowdown for the modulating pilot valve assembly is minimal. Most modulating pilot designs will have a worst case blowdown of 3% to 4% for either gas, liquid or multi-phase applications. In multi-phase applications this can provide an advantage over the direct acting spring loaded valve especially when the quality of the gas portion of the fluid is high which can create a blowdown as much as 20%.
