Bobco Gauge Package – The Most Accurate Gauge Reading Possible
Mounting two similar standard pressure gauges on a PUMP, one on the PUMP inlet and one on the outlet, is a common method of determining pump operating condition. Unfortunately, this presents two significant problems for the person servicing the pump. First, accuracy errors in this method are compounded. Instead of having the rated accuracy of the one pressure gauge, of say 2 percent, the error would be doubled to 4 percent.
Second, and this is possibly the bigger issue, many operators have not been trained as to why there are two pressure gauges on the pump. History shows that many operators when asked why there are two pressure gauges simply cannot answer the question. Very often the operators have no idea that they are supposed to subtract one pressure gauge reading from the other. Even if they do, they may not truly understand the importance of that calculation.
Bobco Gauge Package
The solution —No math, no mistakes andeasy to understand
The Bobco Gauge Package is designed to give the most accurate gauge reading possible on a centrifugal pump. Differential pressure gauges can greatly reduce system operating errors, improve system efficiency, protect expensive equipment, and reduce maintenance time. When used with the Flow Conditioning Corporation’s Hydronic Indicator Gauge, readings are given directly in feet of head eliminating the need to convert from PSI. The shut off valves and fittings are all brass construction. The hose is constructed of synthetic rubber tube which is textile braid enforced with a synthetic rubber cover.
One differential pressure gauge, installed using the same taps at the pump inlet and outlet, can eliminate the problems noted above. By eliminating the use of two gauges, the rate of error will drop to the accuracy rating for the single pressure gauge. The operator would also better understand the reading, without having to know to “do the math.”
Monitoring differential pressure reduces confusion, errors, and inaccuracies and presents conditions on a single, easy-to-read dial. In addition, switches or transmitters can be added to allow for local and remote monitoring in one unit.
Hydronic equipment is an important cog to any buildings proper use and function. To maintain and operate this equipment, they can be protected by a low-cost Bobco Gauge Package. Please contact us and we will help design and recommend the best package for your applications.
