MFM / GAS FLOW
Product appearance varies by configuration.
Mass Flow Meter (MFM)
KM1000 Series
The KM1000 Series gas mass flow meter uses a solid-state sensor for stable measurement with a linear output. Analog and digital output options are available. Applications include photovoltaic equipment, vacuum pumps, analytical instruments, spectrometers, and medical equipment. See the datasheet for response time, flow range, and shock resistance.
