Accurate leak tests validate the safety of the process, preventing manufacturing errors and hazards. By using a combined pressure & mass flow instrument, leaks are detected quickly and reliably. Set the desired pressure setpoint, measure the flow and detect the leak without waiting time. <\/p>\n\n\n\n
-Multivariable control. Create a stable pressure and measure the flow with an \u201call-in-one\u201d instrument.<\/p>\n\n\n\n
-Low pressure drops minimize restrictions and enable rapid pressure stabilization resulting in a much faster leak test than pressure drop testing.<\/p>\n\n\n\n
-Reliable control and measurement from 0.01% to 100% of full scale.<\/p>\n\n\n\n
Looking for a quick and accurate way to leak test your system? Alicat Whisper controllers with low pressure drop provide a convenient solution with a single instrument. A standard controller will also work but stable leaks are best detected when the instrument generates minimal pressure drop. This makes the low pressure drop (as low as 0.07 PSID) of a Whisper very useful, especially when leak testing smaller volumes such as valves or sensors.<\/p>\n\n\n\n
An Alicat mass flow controller displays flow, pressure and temperature readings simultaneously and can control either flow or pressure. In an installation like the one shown in the picture, a single Whisper controller can maintain a constant pressure at the device under test (DUT-Device Under Test) while providing accurate mass and volumetric flow values in real time. When the DUT is subjected to a constant pressure in the closed system, the measured flow is a direct measure of the leakage.<\/p>\n\n\n\n
