Chemical Control Equipment
Chemical Control Equipment Monitors and Controls Chemical Feed and Bleed
The flow chart below shows the interaction of various types of chemical control equipment. This equipment is used to monitor and control chemical systems:
Follow the arrows to see how the control equipment interrelates.

A sensor measures and identifies a parameter. So one type of sensor may be a pH sensor, which senses the pH in the system. Another type may be a water meter. The water meter inputs the number of gallons of makeup water of the system to the controller.
The controller receives that input information. And then it generates an output to operate different types of equipment. That equipment may be a motor operated valve, a pump, or some other type of functional equipment.
The operator inputs settings and parameter changes into a phone, laptop or other computer which directly affect the operational controls of the controller.
The computer generates logs and graphs from the data received from the controller. The computer operator can print this data in many forms.
Another type of sensor is the barrel sensor. It supplies chemical level data to the controller. Barrel level information may also be graphed.
