工艺温度影响■ 对于质量流量测量，过程温度影响定义为由于过程温度偏离校准温度而引起的传感器流量精度规格的变化。温度对流量的影响可通过在正常工作温度下调零进行校正。使用零点验证工具优化零点校准。■ 对于密度测量，过程温度影响定义为由于过程温度偏离校准温度而引起的密度精度规范的变化。所有模型的工艺温度影响模型质量流量密度每°C大质量流量的百分比g/cm3每°C kg/m3每°C CMFS007±0.0006±0.000015±0.015 CMF010、CMFS010、CMFS015±0.0002 CMF025、CMF050、CMF100、CMFS025、CMFS040、CMFS050、CMFS075、CMFS100、CMFS150±0.0001 CMF200、CMF300±0.0005 CMF350、CMF400±0.0008 CMFHC2、CMFHC3，CMFHC4±0.000075注：对于订购了可选DT温度校准（参考密度校准）的型号，密度规格在0至140.0°F（60°C）之间有效，当高于或低于此范围时，应考虑工艺温度影响。过程压力效应过程压力效应是指由于过程压力变化偏离校准压力而导致传感器质量流量和密度精度规格的变化。这种影响可以通过动态压力输入或固定仪表系数进行校正。具体仪表压力补偿系数见校准表。如果未提供压力补偿系数，则使用下表中列出的典型值。有关正确的设置和配置，请参阅www.emerson上的变送器配置和使用手册。com/流量测量。CMFS模型的工艺压力影响模型质量流量（%）密度每psi每bar g/cm3每psi每kg/m3每bar CMFS007、CMFS010、CMFS015无无无无无无无无无无CMFS025无无-无-0.000004-0.054 CMFS040-0.0003-0.005–0.000013–0.187 CMFS050 M–0.001–0.015-0.0000247–0.358 CMFS050 H/P无-无-0.0000034–0.049 CMFS075–0.0007–0.01-0.0000255–0 0.37

Process temperature effect ■ For mass flow measurement, process temperature effect is defined as the change in sensor flow accuracy specification due to process temperature change away from the calibration temperature. Temperature effect on flow can be corrected by zeroing at normal operating temperature. Use the Zero Verification tool to optimize the zero calibration. ■ For density measurement, process temperature effect is defined as the change in density accuracy specification due to process temperature change away from the calibration temperature.

Process pressure effect Process pressure effect is defined as the change in sensor mass flow and density accuracy specification due to process pressure change away from the calibration pressure. This effect can be corrected by dynamic pressure input or a fixed meter factor. See the calibration sheet for the specific meter pressure compensation coefficient. If no pressure compensation coefficient is provided, use the typical values listed in the table below. For proper setup and configuration, see the transmitter's configuration and use manual at www.emerson.com/flowmeasurement.
