Power Sprayers | Power Sprayer Pressure Gauge | Termite Control Sprayers
Most of the gas powered sprayers we build include a pressure gauge to allow the technician to know the pressure at which the system is operating. For most customers, this is satisfactory.
Here is a photo of what this can look like:
A couple of considerations for this design:
- Make sure the gauge is facing the correct way so the tech can easily see the pressure from where he/she normally operates the sprayer.
- Make sure the face of the gauge is not blocked by the sprayer frame or other components.
- Make sure the gauge is the proper range for the power sprayer. For example, for a roller pump that operates from 0-150 PSI, we usually use a 300 PSI gauge so that the operator can easily read the pressure. If we put a 1000 PSI gauge on the sprayer, it would be difficult to accurately read the pressure because the scale is too large.
Occasionally a company owner wants to know the pressure at the end of the hose. The pressure is usually lower at the end of the hose because of the pressure loss (due to friction) of the water moving through the hose. It is usually on termite control sprayers that we receive this request.
Here is a photo of how we prefer to put the pressure gauge at the hose end.
By putting the pressure gauge on quick disconnects,
it can be safely stored when not in use. If the gauge were hard plumbed, we fear it would be damaged when the hose is wound up.
- Put the gauge on quick disconnects for easy and safe storage.
- Install the gauge on hose end to measure hose end pressure.
- Lock the pressure gauge in vehicle or toolbox for safe keeping when not in use. Wrapping the gauge in a towel to cushion and protect it is not a bad idea.
- When you check the pressure, remember this is the pressure for the existing configuration:
engine speed, pump RPM, hose lenght,
spray gun, spray tip, etc. If any of these items change, you must remeasure the pressure.
