Mass flow meters

The L30 is the latest addition to the LIQUI-FLOW series of thermal mass flow meters/controllers. Its maximum measuring/control range is increased from 20-1000 grams/hr to 0.4-20 kg/hr, at pressures from vacuum up to 100 bar. The instrument is constructed around an easy-to-clean 316L stainless steel tube with a thin-film thermopile heater/sensor fixed on the outside of the tube. In the sensor, the liquid is heated only a few degrees above its incoming temperature, so the risk that the liquid will decompose or gas-out is negligible.
