Flowmeters are equipped with built-in 6-ring needle valves, 16-ring high-precision metering valves with "non-ascending stem", or may not be equipped with any valves. As long as high sensitivity control and high resolution are required, especially when used in conjunction with metering tubes for measuring very low flow rate, high-cost high-resolution valves are worth the money. Generally speaking, when measuring gas, it is recommended to install the valve at the entrance (bottom); when measuring liquid, the valve can be installed at both the entrance and the exit (top). For vacuum applications, valves must be installed at the outlet. If not specified at the time of ordering, the valve will be installed at the inlet of the flowmeter at the time of shipment.
