Teravalve introduces new water conservation valve
TeraValve has developed a patented water savings valve that could save 'thousands of dollars' in water and sewage bills for commercial water users. The company also offers a performance guarantee after conducting a comprehensive audit by their water conservation specialists. Besides installing the system, TeraValve also offers to monitor, control and report progress 24×7.
Water while flowing through the meter activates an internal paddle to spin so as to measure the volume of water consumed. But water also has an inherent volume of air in it which is also measured when measuring the volume of water as there is no mechanism to distinguish water from air. As a result, users end up paying for air as they pay for water. Another problem with the water systems is that they are delivered at varying pressures opening/closing for fixtures like sprinklers, toilet sinks, etc. When this pressure rate drops, air fills in to create more volume and increase the flow. This causes the paddle to spin more and increases the user's water bill. Many water users also receive water supply at pressures above 65 psi. This mismatch between the rated pressure and the actual pressure results in over consumption. Pressure reducers are employed they need regular maintenance and fail without being detected. This also affects the sewer bill as users are charged on a multiple of the water that comes from the facility.
The TeraValve water conservation valve is based on fluid dynamics. The device compresses air before it reaches the water meter thereby removing its volume and causing it to be discounted whilst measuring water usage. The device also acts as a buffer against surges thereby maintaining the water flow level. The system's variable flow control regulates flow without changing the pressure thereby reducing the need for independent flow regulator systems installed on water fixtures. It also corrects water meter measurement by reducing over spinning.
'Le Chatellier's principle of volumetric dynamics and Boyle's law on gas pressure and volume has been adopted in the design and construction of TeraValve. When installed close to the water meter, air reaching the pressure point gets compressed and loses its volume. Thus, air passing through the water meter remains in its compressed form until it reaches the TeraValve device and then regains its original state afterwards and is hence not measured,' says a spokesperson for the company.
