An orifice is a small opening that restricts flow in a fluid system, leading to a decrease in pressure as the fluid passes through. According to Bernoulli's principle, when fluid velocity increases as it flows through the orifice, the pressure drops. This pressure drop can create a differential pressure that can be used for measurement or control in various applications. Additionally, the size and shape of the orifice can significantly influence the flow rate and behavior of the fluid.
A device used to measure the flow of liquids in pipelines and convert the results into proportional electric signals that can be transmitted to distant receivers or controllers. a velocity over a known surface area is measured and then it can be converted to volumetric flowrate or mass flowrate if the density of the fluid is known.

Flow rate cannot be converted into pressure units. So, you should give up the idea.
Both pressure and flow decreases
To convert volumetric flow rate in cubic meters per hour (cmh) to static pressure in Pascals (Pa), you will need to know the characteristics of the fan or blower generating the flow. You'll need to refer to the fan curve provided by the manufacturer, which shows the relationship between the volumetric flow rate and the static pressure. By interpolating on the fan curve, you can determine the static pressure corresponding to the given flow rate in cmh.
You can't. Pascals (pa) area messurement of pressure. CFM (cubic feet per minute) is a rate of flow. However, there is a device called a manometer which is used to measure either pressure(in pascals) or air flow in(in cubic feet). Most commonly used for blower door tests.
its pressure between suction and discharge flow...
Yes, the differential pressure switches off the thermopac. Differential pressure switch shut off unit in case of abnormal thermic fluid flow condition.
nLPM stands for Normal Liters per Minute. This is actually a mass flow rate because it describes the amount of gas that would have the indicated LPM volumetric flow rate AT 1 atmosphere pressure and 0 degrees C. The actual volumetric flow rate (LPM) at any other temperature or pressure condition must be adjusted according to the ratios of absolute temperatures and (inversely) absolute pressures.
The volumetric flow rate through a pipe is not directly affected by the height difference between two points in the system. Volumetric flow rate is primarily influenced by factors such as pressure difference, pipe diameter, fluid viscosity, and fluid density. However, height difference can affect the pressure head in the system, which in turn can impact the flow rate through the pipe.
To convert flow to pressure in a fluid system, you can use the Bernoulli's equation, which relates the flow rate, pressure, and velocity of the fluid. By manipulating this equation, you can calculate the pressure based on the flow rate in the system.
Mass flow is the amount of mass passing through a given point per unit time, while volumetric flow is the amount of volume passing through a given point per unit time. Mass flow takes into account the density of the fluid, while volumetric flow does not consider the density of the fluid.
The differential pressure in a fluid system is calculated by subtracting the pressure at one point in the system from the pressure at another point. This difference in pressure helps determine the flow rate and efficiency of the system.
To convert flow rate to pressure in a fluid system, you can use the Bernoulli's equation, which relates the flow rate, pressure, and velocity of the fluid. By rearranging the equation and solving for pressure, you can calculate the pressure based on the given flow rate and other relevant parameters of the system.
Differential pressure transmitters were originally designed for use in pipes to measure pressure before and after the fluid encounters a filter, pump, or another interruption in flow. Standard differential pressure transmitters come with two process connections arranged side by side to measure the drop in pressure (d) between the higher and lower points (H and L, respectively, in Figure 1). Classic differential pressure transmitters can also measure flow rates. It wasn’t long before people realized that differential pressure measurements could be used to determine liquid level as well.
Pressure Differential Valve- maintains a constant Differential pressure across it. Say if P1 was inlet pressure and P2 was outlet pressure PDV will try to keep constant DP. Say if P2 increases due to some reason and P1 is constant the DP will decrease and will decrease flow through the PDV. At this point to maintain the constant DP PDV will open and allow more flow through to keep the flow constant and thus DP constant.
