What is compound gauge measurement range?

Measuring Range: -760 MMHG / 1 BAR / KG/CM2 UP TO 40 BAR/KG/CM2. Usage/Application: Industrial. Type: ANALOGUE.

How do you measure the performance of a centrifugal pump?

Measuring performance The performance of centrifugal pumps can be seen by comparing the total dynamic head (TDH) to the flow at a given speed (Figure 5). TDH is the total resistance to flow that exists while the liquid is in motion. By using a gauge, both TDH and the speed of the flow can be measured.

What are the pump gauges?

Pressure Gauges on the discharge of a pump are of a type which displays pressures in set ranges, for example between 1-10 bar, or 1-15 bar. Gauges on the suction part of the pump are typically a compound gauge meaning they read both positive and negative pressures.

What is the main function of centrifugal pump?

The main function of centrifugal pumps are to transfer energy. Explanation: Centrifugal pumps are used to transport fluids. They transport fluids by conversion of energies. Centrifugal pumps are a sub class of dynamic axisymmetric work absorbing turbomachinery.

What is the use of compound gauge?

Simply put, a compound gauge is a device that can display both positive and negative (vacuum) pressures. You need to use a compound gauge when you are measuring a system that is exerting both positive and negative pressure on the gauge.

How do you measure the efficiency of a pump?

The booster pump efficiency is determined by subtracting the inlet pressure into the booster from the discharge pressure and using the flow rate from the well. The electrical panel must be opened and power meter readings for each pump taken to determine input horsepower.

Is pump pressure absolute or gauge?

An absolute pressure gauge reports absolute pressure. All values are positive above zero. And vacuum is a positive number less than atmospheric pressure. As a liquid accelerates into the suction nozzle of a pump, the liquid frequently drops into vacuum as the velocity increases.

What is read on a compound gauge?

The diaphragm on a compound unit will measure vacuum pressure, which will read as a negative psi on a digital gauge, or often in inches of mercury (inHg) on an analog gauge. So 7.5 psi on an absolute pressure gauge would read -7.5 psi on a compound gauge at sea level.
