Flowmeter is one of the instrumentation sensors used to measure the volume or mass of fluids. We know flowmeters by other names such as flow indicator, mass meter and flow sensor. The Flowmeter MFS 20-200 l/min produced by Grundfos company is used in INRO ACRC301S coolers of data centers. The supply voltage of MFS 20-200 l/min is 5 VDC. The maximum pressure of the system can be 24 bar. It is one of the important spare parts of Schneider machines in data centers.
