Abstract: A method and system to precision dose a fluid system with an injection fluid having chemicals is provided. The method and system includes providing a buffered dosing tank of a known geometry between a source tank and an injection pump. The fluid level detector measures the pressure of the dosing tank to determine a fluid level. The fluid level together with the known geometry allow for a controller to calculate a fluid volume in the dosing tank and a change of volume over time. Using the change of volume over time, the controller can calculate an actual dose rate and adjust a speed or duty cycle of the injection pump such that the actual dose rate is approximately the target dose rate.
Abstract: A dynamic compressor control is provided. The dynamic compressor control includes sensors to sense operating parameters of a compressor and a compressor analytic software package. The compressor analytic software package uses the sensed operating parameters of the compressor to generate key performance indicators. The key performance indicators are used to calculate process variables for the compressor. The dynamic compressor control uses the sensed operating parameters and the process variables calculated from the key performance indicators to provide operating alarms and/or shutdowns.
Abstract: A chemical tank level system for a wellbore chemical injection tank is provided. The system includes a pressure sensor is located downstream of the chemical injection tank where the fluidic pressure is essentially the same as the fluidic pressure at the base of the chemical tank. The pressure sensor sends a signal indicative of the fluidic pressure to a tank level sensor module. The tank level sensor module receives the signal from the pressure sensor. A processor takes a series of pressure sensor signals over a sample window and calculates an average of the signals over a defined time window.
