USPTO (United State Patents and Trade Mark Office) has already issued a patent vide patent number 9,038,669 B2 in the month of May, 2015.
Patent application(s) in ‘European’ and ‘China’ patent office are under examination.
In India patent office; examination is yet to begin.
Mr. Sunil Mittal, inventor owns IPR’s in this matter.
A Private Limited Company incorporated in India: Mittal Intellectual Properties OPC Private Limited .
Inventor has invested a sum of INR 100,000/- in the company in the form of capital (10,000 shares @ Rs 10/- each).
It is very easy to manufacture this product, with the help of non-skilled workers.
For manufacturing of this device, an investor needs a small building; an electricity connection; block(s) of device; molten metal(s); grinder & polishing machine; and un-skilled workers.
However, to manufacture a tailor made device to suit a specific purpose; there can be a need of lath machine(s) too

  1. This device is very robust. It has no moving part, therefore has a very long useful life (that too without losing on its work efficiency with passage of time); and has negligible or almost no maintenance cost;
  2. It can easily be installed in an indoor or outdoor applications;
  3. It can be manufactured in any shape and size to provide a tailor made solution to a specific consumer;
  4. It can be manufactured with a material which is impermeable to the flowing fluid and also is capable to withstand with the stress to be developed therein during its use;
  5. It can be fitted or retrofitted into any new or existing network;
  6. There is no need to install a PRV (Pressure Reducing Valve); and/or a shut-off valve; and/or a filter etc. at upstream or downstream of this device;
  7. Essentially, no pre-treatment like heating, pumping etc. of a flowing fluid is required; and
  8. Essentially, no additional equipment or source of energy is required for its use or operation;
Just Fit it and Be at Ease.

video tap 1 and tap 2 have been opened, partially or full?

Both these taps have been opened to their full capacity; so that these taps can deliver maximum possible flow rate at their downstream.
: Yes, because flow rate at downstream of this device is dependent over the dimensions of the device. Therefore, if the dimensions are increased or decreased; the available flow rate at downstream of this device will be increased or decreased, respectively.
It is to be fixed for a particular unit of a product.
Yes, but it will be limited upto the maximum flow rate, which can be achieved with that dimension i.e. the designed flow rate.
No, there will not be any need to install a PRV (pressure reducing valve) at the entry point or at any other point.
: No, the efficiency of device or availability of flow rate at downstream of the device will be almost un-variable/ un-changed for a sufficient longer time, because present device has no moving part or spring etc. Efficiency may get hampered when dissolved impurities present in the water get settled within the device. Such a possibility can happen, only when there is no water flow across the device for a sufficiently longer time. However, such malfunctioning of device can easily be corrected by a plumber.

video, when innovator open last tap or tap 3; the pressure drops substantially in the main line. How this effects, available flow rates at downstream of other tap(s) connected with this entry point?

Available Flow rate, at downstream of different tap(s) varies, substantially. Flow rate is much higher near to entry point or source of supply and it is 'very low' or 'negligible' at the 'tail end' of pipeline network. Watch Video tail end problem and Solution to tail end problem
From video, it is evident that when innovator open tap 1 and/or tap 2; pressure drops ‘very marginally’ in the main line; which ensures availability of almost equal pressure at the back of all tap(s) connected with a defined pipeline network and hence results in availability of equal water at the downstream of all tap(s).

Video does not show or confirm the above statement? Whether it is a hypothetical imagination/statement by innovator?

No, this is not a hypothetical imagination/statement by innovator. But, by conducting another field test he has proven the same. Watch Video tail end problem and Solution to tail end problem
Yes, the present device can easily be retrofitted into all existing systems; subjected to the existing system can withstand with the stress to be developed therein, during use or operation of present device.
No, it is useful for various activities; where there is a need for simultaneous reduction of pressure and flow rate.
No, it is equally good for indoor as well as outdoor installations.
: There is no specific need for a material. This device can be manufactured with a material which is fluid resistant and is capable to withstand with the stresses to be developed in it during its use.
: Yes, it can easily be manufactured in any desired shape and size to fulfill the requirement of a consumer.
: No, in general it is to work under inherent energy conditions.
No, up-to an orifice diameter (d1 or d2) ≤ D/5; there is no or negligible pressure drop in a pipeline network. However, when orifice diameter (d1 or d2) ≥ D/5; there is a minor pressure drop in a pipeline network; the same can easily be noticed/ observed in the flow rate available from an outlet. However, pressure drop in a pipeline network after installation of this device would be much lesser than a pipeline network where present device is not installed.

Where d1 or d2 = the diameter of orifice; and

D = diameter of tubular structure
Yes, if we need equal distribution/ flow rate from all outlets; we need to install device of same size prior to each outlet. However, where there is no such requirement i.e. to obtain different flow rates from different outlets, the device having different sizes can easily be installed.
No, essentially there is no need for any additional equipment or source of energy for its use, operation because generally it is to work under inherent energy conditions.
The Flow rate “Q” at downstream of a device is the function of ‘square root of inlet pressure’. Q = K × √p Where K = Flow Coefficient; and p = inlet static pressure This relation is true for other known flow meters i.e. ‘orifice’; ‘nozzle’; and ‘venturi-meter’, too.
These flow meters i.e. ‘orifice’; ‘nozzle’; and ‘venturi-meter’, causes single stage resistance to the flowing fluid; whereas present product causes three stage resistances to the flowing fluid and results in reduction in pressure and flow rate of a flowing fluid, simultaneously. Also, in present case value of flow coefficient ‘K’ is much lower than other flow meters.
