The APM-PROC-APO features a strikingly visual, easy to read, display and a versatile range of analogue inputs, this Process Meter takes APM into a
wide range of new industrial applications.
The user programmable scale and customized annunciators mean users can specificaly tailor the meter to display their critical parameters exactly to what they want, whilst the dynamic backlighting, combined with set points, means users are instantly, visually alerted when the measured input is out of range. The two outputs can be used to integrate into other systems, such as SCADA and BMS.
Innovative design technology brings a greater level of accuracy to the APM range through input signal optimization. An accuracy of 0.1% or better can now be achieved, allowing for more precise measurement, digital display and control. Non-linear sensors, from devices such as pressure transducers, can also be used thanks to the new APM Configurator application that allows the user to configure upto 20 points in a non linear conversion table.
The APM Process digital panel meter is used to display the volume of liquid in the tank. The 4-20mA analog output from the liquid level sensor is scaled to gallons, and the custom annunciator set to "Gal", all via the easy-touse software application. High and low setpoints are configured so that the normal green display will flash red when the tank is too full or empty, alerting the operator. Additionally the APM digital outputs are integrated into the tank pumping system and the tank is automatically drained or filled if the setpoints are exceeded.
The APM-PROC-APO Process Meter is used to provide digital display of the material volume in the
silo, using the analog output from a
The signal from the sensor is scaled into the measurement units cubic metres, and the annunciator customised to m3 , all via the easy-to-use software. Due to the irregular shape of the silo, the 20-point non linear table is used to correct the non-linear signal from the sensor.
The displayed value accurately shows the volume in the silo. High or low setpoints can be set, and the APM can be integrated into other systems for process control.
