The thermistor monitors the temperature of the water so that the PCB (printed circuit board) knows whether to increase or decrease the temperature depending on the demand. Should the thermistor fail then that could lead to the temperature of the water getting too high and result in the boiler overheating as a result.

Where boilers are operated without constant supervision (which includes the majority of industrial boilers) low water level alarms are required to shut down the boiler in the event of a lack of water in the boiler. Low level may be caused by: A feedwater shortage in the feedtank. Failure of a feedpump. Accidental isolation of the feedwater line.

For this reason, Flowline suggested the use of our guided wave level sensors that are unaffected by scaling build up and ideal for high temperature and pressure applications in metal tanks. The guided wave sensor provides reliable level data to the controller, which in turn, monitors the water level and transfers it to the boiler.

Therefore, in this situation, one would expect the control valve to hover near the fully-closed position, allowing just enough water into the boiler to keep the steam drum water level at setpoint. If, however, there is a high demand for steam from this boiler, the rate of evaporation will be much greater.

To maintain the temperature throughout the system, hot water recirculates between the boilers, storage tanks and tenants. The tanks are hot, humid environments, dripping with condensation. The integrator wanted the longevity of using a non-contact level solution, but they had experienced problems with ultrasonic sensors in condensation, and they couldn't afford pulse …

GET A QUOTE High water alarm - The alarm operates if the water level rises too high, informing the boiler operator to shut off the feedwater supply. Although not usually mandatory, the use of high level alarms is sensible as they reduce the chance of water carryover and waterhammer in the steam distribution system.

Regulating amine feed between 8.8-9.2 pH range in a mixed copper-iron condensate system is an example of this. There are two approaches to measuring pH here. Both methods work. Both have benefits. The first is to install the pH sensor into the hot process line. The system requires a pH controller, sensor, mounting hardware, amine feed pump
