Tank and Well
Remote Control for Water Systems
The Mission Tank and Well System maintains the water level in a storage tank by automatically sending commands that signal remote well or booster pumps to turn on and off. The system relies on standard Mission remote terminal units (RTUs) and a transducer to measure the tank level. There are no radio networks, computers or programmable logic controllers (PLCs) to maintain. It is low cost and easy to set up.
How It Works
The MyDro RTU at the water tank continuously transmits level information to a nearby cellular tower. This RTU may be connected to other equipment such as chlorine monitors or other alarm inputs. It can be battery powered with the MyDro 50 or even solar powered with the MyDro 850 (no like power needed). Status data packets are transmitted through a secure private network connection to Mission servers. When the tank level is outside the user configurable level boundaries, a command is automatically sent to output relays on the RTU where the pumps are to energize pumps or valves and refill the tank. The Tank and Well software supports up to five pumps.
Real–time notifications and reports inform operators of high pump starts, excessive pump runtimes, AC failure, low battery, and more. The 123SCADA web portal allows an operator with appropriate security credentials to adjust the pump on/off trigger levels and view current level readings. Trending graphs and reports are accessible on desktops and through the 123SCADA app on smart phones and tablets.
Optimization and Money Saving Features
The software includes a virtual pump alternator feature which cycles through each well pump connected to a Tank and Well system. It can be set up to evenly distribute pump runtimes across all wells.
Maximum runtimes can be set for each pump, and the system will alternate to the next pump once the maximum runtime is reached. This reduces the risk of damaging the water table by over pumping.
An off–peak force fill feature is available to save money by filling a tank when electricity rates are lower than peak hour rates.
Behind–the–scenes business logic is available to notify of abnormal situations that can affect system performance. For example, a “call–to–run fail–to–run” alarm notification can be dispatched by the system if the well pump does not run when commanded. This could happen if the well is without AC power, an operator has locked the pump out locally (typically with the hand–off–auto (HOA) switch), or the pump requires service (motor inoperable).
