Provider of fluid flow measuring solutions that depend on Reynolds numbers. It doesn’t matter if it’s averaging pitot, concentric or eccentric orifice plate, flow tubes and nozzles, or pitot tubes.
A differential pressure measuring solution can be at the top of the shopping list if the operators deem a pressure drop in the system tolerable. The requirements for this could be based on both practical and financial considerations.
An averaging pitot tube using Bernoulli calculations can be supplied in different configurations according to the client requirements. Variations in material, insertion lengths, connections and flange types. Options for manifold vales to isolate, equalize and vent.
In a differential pressure type flow set up we see the rate average calculated by the change in pressure drop. The flow is measured by the difference between the average total pressure and static pressure of the sensor in the fluid (that is, the pressure difference). It is commonly used to measure the flow of liquid, gas and steam.
- Balanced orifice type
- Cone flow meter
- Standard orifice plates
- Standard nozzles
- Averaging pitot tube flow meters
Instead of using a differential pressure gauge, operators who monitoring filters can buy a DP transmitter and achieve the same results, except that an output to a remote pressure indicator can be wired to the device.
Scaled output can be expressed in Pascal Bar ATM Torr and PSI but the most common units of differential pressure measurement are in PSI and bar.
Consider other applications that require a low cost and yet simple solution: One being the pressure monitoring of ventilators which is becoming more important as health and safety standards are requiring designers to build in a system of reporting for the status of the vents i.e. if they are actually working according to the required specification.

Another safety issue could be overpressure monitoring. Too much positive pressure in a room could mean that air will only travel one way. A clean room or clean air system always needs good ventilation and an overpressure situation that has been identified will give opportunity to remedy the situation through a practical design change.
