In case the regulator is big for the applications, the poppet and the seat can be too large and this will allow too much flow inside. Each time that the regulator is opened, then it will leave much flow than expected. The regulator needs to be selected based on the sizing fact. The pressure is found in the like on or off valves and it is involved once again. Sizing a regulator afterwards, it can be too difficult compared to sizing other types of the valves. However, it does not mean that it is impossible since it can still be done. Before you choose the size of the regulator, you have to consider three things. The inlet pressure that will be used within the regulator, the pressure that you will need within the Pressure Regulators and the flow needed for the downstream.
If you have already such information, then you have to know the size of the regulator that you need. A theory behind the size of the regulator, it is to calculate the pressure drop across the required flow and to compare it to reach to the required drop. The pressure drop is normally less than the pressure drop that it is necessary in case the application is the right one. Another way to know if the size of the regulator is enough is to calculate how much flow that may pass within it.
If you are looking for the Pressure Sensors also, there are things that you will have to keep in mind. The right supplier may help you in selecting the right equipment for the applications that you may be having. It is good to get the sensors from a supplier who has the experience and the knowledge so that he can assist you in what you are doing. If you have already decided on what you are going to measure such as the gas or fluid, it is important to decide if you are looking for the transmitter or a transducer. Normally, the difference is found in the output. You have to be aware of the testing environment before you buy the sensors. If you are considering the capacity of your pressure range, you have to know if you are looking for vacuum scale or positive of the measurement.
You have also to know your needs before you decide on the sensor you want to use. For example, you may be looking for a sensor that it is found in a certain budget. You have to know what you may be losing or gaining if you choose a sensor of high or low price. You may also have to consider the output of the pressure like digital output. You have to keep in mind that a constant feedback of zero pressure may be hard to let you know that there is no pressure or if there is a problem with the pressure sensors. The sensor should also be able to communicate in direct way to the micro controller even if there is no external converter of analog to the digital.
