Bubbler systems are ideal for level measurement of open channel run off systems or duct and tank situations where debris, foam, steam, or surface turbulance makes standard methods of level measurement impractical.
A boat builder requires to display the amount of fuel in an irregular shaped tank using a level sensor. As the output from the level sensor is not linear, a bargraph programmable meter controller is installed to linearize the signal. The digital display shows the amount of fuel in liters, while the bargraph display shows this as a percentage of the tank capacity.
O2 is an important parameter to measure and control in kilns and furnaces. The diagram below shows the Tiger 320 Series DI-50 controller connected to a Zirconia O2 sensor with a built-in thermocouple.
The controller calculates the O2 level from the temperature and mV level of the sensor. The result is then displayed on the controller.
Our customer has a semi-automated mixing tank and uses a level sensor to detect the tank level. The tank is filled with a primary solution to a reconfigurable percentage of the full tank, controlled by a setpoint. A secondary solution is then added by hand.
Texmate installed a Tiger 320 Series DI-60AT programmable meter controller (PMC). The controller is calibrated to display the percentage in hundredths of a percent (000.00%). When the pump fills the primary solution to the selected percentage, the setpoint relay stops the pump and the controller scrolls the
