KROHNE, Inc (Peabody, MA)
Manufacturer krohne.com/en/products/flow-measurement/flow-controllers/ The DWM 1000 electromagnetic flow switch and the DWM 2000 electromagnetic flow meter monitor the flow of electrically-conductive liquids, pastes and slurries. The DWM 1000 uses an induced voltage converted into a switching signal. The DWM 2000 uses an induced voltage converted into a 4...20 mA current output that is proportional to the flow velocity. The DW 18 series of flow controller is ideal for locally indicating the flow of homogenous clean liquids. |

Sierra Instruments, Inc. (Monterey, CA)
Manufacturer Sierra's mass flow controllers can measure mass flow rate of any clean dry gas including mixtures, toxics and corrosives. This product line utilizes "Capillary Tube Thermal" sensing technology and are widely used for precise measurement of very low flows (i.e. 0-10 sccm) as well as higher full scale flow ranges up to 1000 slpm. |

| Alicat Scientific, Inc. (Tucson, AZ)
Manufacturer Flow controllers range from 0.5 CCM full scale to 1,500 SLPM full scale and all flow control devices include a dynamic digital display that simultaneously shows all the process parameters being measured by the meter plus a push button operator interface for set point adjustment, gas select and tare. |
| VICI Valco Instruments Co. Inc. (Houston, TX)
Manufacturer, Contract Manufacturer, Distributor, Service Company Flow controllers provide a stable flow rate under varying pressure. An upstream-referenced controller maintains the flow rate as long as the upstream (inlet) pressure is held constant, while a downstream-referenced controller maintains a constant flow under constant downstream (outlet) pressure. |
| Bowman Industry and Manufacturing LLC (Tucson, AZ)
Manufacturer The BI-3000 series of Gas Mass Flow Controllers and the BI-4000 series of Gas Volumetric Flow Controllers provide +/-1% full scale accuracy and 0.5% precision, controlling all traditional inert gases and most aggressive gases. |
