Conductivity sensors don’t “physically or electronically” vary significantly over time. The temperature compensation resistor is the only item that has a variable value in the sensor itself. Everything else is a straight ahead mechanical arrangement (Red and Black wires connect…
What Is K Factor In Water Meters?
Is my Paddle wheel or Magnetic water meter giving me the correct Signal and ratio for flow gallons/liters flowing through it? We’ll walk you through water flow meter calculation. Well, here is a test you can do in the field.…
Flow Switch Problems
I get several calls per month on Flowswitch operation. Typically, I hear “my controller shows no flow, but there is plenty of pressure in the line”, or “my controller shows flow, but the system is shut down”. Our Flowswitch does…
Troubleshooting Boiler Conductivity Sensors
The main cause of boiler sensor failure is steam exposure. Our SR2 series sensors, both Standard and Harsh Duty, are not designed for a steam environment. When a boiler plumbing set-up is not optimized, damage to the sensor can be…
Troubleshooting 2-Electrode Conductivity Sensors
Cooling tower sensors come in either 2 electrode or 4 electrode versions. The 2-electrode sensors are used on the model 140,1575e, and newer Nexsys controllers. They were also used on the old 100 series (101,111,151,161) and some pre-2000 series controllers.…
