ABSTRACT:
A chemical injection system has a pump and an actuator connected to the pump. The actuator further comprises a first sensor for sensing a deactivated state of the pump; a second sensor for sensing an activated state of the pump; a computer connected to the first and second sensors and the actuator; and an interface connected to the computer, to receive commands from, and to transmit data to, a control point. The computer further comprises a stored program. The stored program contains instructions to energize the actuator to cause the pump to dispense a pre-determined quantity of chemical and to verify that the pump has actually operated to dispense the pre-determined quantity of chemical.
