Abstract
Systems and methods relate to measuring ammonium bisulfide concentration in a fluid sample. The system includes an electrolytic conductivity cell, a temperature sensor and an analyzer. Logic of the analyzer determines the ammonium bisulfide concentration based on signals received from the conductivity cell and the temperature sensor that are coupled to monitor the fluid.
Claims8
A system for determining ammonium bisulfide concentration in an aqueous liquid stream, comprising:
- a conductivity cell configured to measure electrolytic conductivity of an aqueous liquid stream that flows through the conductivity cell;
- a temperature sensor coupled to measure temperature of the aqueous liquid stream, wherein the temperature sensor is inserted directly into the aqueous liquid stream;
- a pressure sensor coupled to measure pressure of the aqueous liquid stream;
- and
- an analyzer operable to receive and correlate signals received from the conductivity cell, the temperature sensor and the pressure sensor to a calibration algorithm to determine an ammonium bisulfide concentration, wherein the calibration algorithm is operable to compensate for any effect of pressure, temperature or both on the conductivity measurement.
