Sensorless Pumping Pump Curves and System Analysis

What You Will Learn

Although the technology is no longer brand new, Sensorless pumping is not yet widely understood. The increased accuracy and reliability create opportunities to improve HVAC systems. Those opportunities start with pump selection but also include the deeper knowledge available to us through flow measurement accuracy. The savings available in equipment investment and long-term operating costs are amazing.

Key topics include:

Sensor location and operating cost savings
Intelligent pump – Performance mapping
Design envelope pump control functions
System performance and energy savings
Value of connectivity and cloud analytics

Key questions answered during the webinar:

How is the setpoint calculated for remote remote-installed differential pressure transmitter?
If there is no sensor, how do you know that you are getting the right pressure from my pumps?
Why do some installations have differential pressure installed on two-thirds of the height of the building?
What about variable speed, variable flow with remote sensor power, and energy savings?
Will parallel sensorless pump control work in a primary variable system with a working standby configuration and in a condenser water system?
Explain the difference between proportional pressure and quadratic pressure.
How does the auto-balancing flow valve work?
Does the system have to be connected to Armstrong’s cloud for Sensorless control?
What information is required from the consultant to Armstrong to correctly select a Sensorless pump?
How is pump efficiency affected by changing the position of the operating point on the pump curve?
If the strainer is clogged and the system pressure goes high, how does the sensorless system understand how to shift the pressure requirements?
What if your central plant is heating multiple buildings, does sensorless technology work or do we need to have a DEPM sensor in each building?
What will be the ROI of the Sensorless pump?
Would this system be practical for a smaller property with hydraulic heating seasonal only?
