Low Flow Liquid Meters
We have a unique capability to measure very low flow liquid rates – from a few gallons per minute to as low as 1 gallon per year (10 cc/day). These low flow meters can measure slurries and most low- and high-viscosity homogenous liquids, including liquid chlorine, magnesium sulphate, sodium hypochlorite, and ferric chloride.
Each flowmeter can be configured from a variety of chemically compatible alloys such as, Quartz, Hastelloy, Monel, Titanium, Tantalum, Inconel, and Stainless Steel. The unique design of these sensors creates an unobstructed path for liquid flow, so nothing makes contact with the fluid except the wall of the tube. Solids in the fluid flow cannot harm the sensor. A variety of standard or custom process connections are available, such as NPT, Tri-Clover, Flanges, or Tube Stubs to best adapt to your existing equipment.
Low Flow Gas Meters
TU and TUL sensors are ideal for measuring low gas flows, whether the gases are explosive, corrosive, dirty, or just too difficult for other meter technologies. Our low flow meters can work with most gases, including ammonia, butane, ethanol, methane, natural gas, and sulfur dioxide.
You can also choose electropolished sensors that can be used to measure ultra high purity gases. These inline gas flow meters are often used on small lines (1″ or smaller) with flow rates ranging from 25 SCFM to a few hundred SCFM.
Duct Flow Meters, Air & Gas
For pipes and ducts from one inch to several feet in diameter, our chemically compatible stainless steel, Hastelloy, or titanium insertion probes provide reliable mass flow measurement. Often used to monitor stack gas, digester gas, and vent air, these mass flow measurement devices are easily installed and designed to provide years of low-maintenance service.
They are suited for use with most non-condensing gases, even explosive and corrosive gases. For areas where little or no straight run is available, the RheoVac™ Flow Conditioner and its unique honeycomb design works to eliminate measurement errors that routinely confound ordinary sensors. A variety of standard or custom process connections are available, such as NPT, Tri-Clover, or Flanges to best adapt to your existing equipment.
Low Flow Controller
The Rheotherm Model 210 Low Flow Controller is capable of measuring and controlling extremely low flow rates with high accuracy and reliability and can be used with most gases and homogeneous liquids with low or high viscosity. The desired flow rate setpoint is set in the flow controller and is easily adjusted by the user at the unit or remotely, and analog output of the flow rate is also available.
Flow Switches
With no mechanical parts, this technology is great for reliable low- or high-flow indication in liquid or gas service. Flow Switches differ from conventional gas or liquid thermal flow meters by changing the state of an output relay once certain flow parameters are met.
Each of our flow switches has an adjustable set point—a minimum or maximum flow rate—and once the measured fluid reaches this point, the device transmits a trip signal to another device (such as a pump) that modifies the rate of flow. Flow switches are often used as a lower cost alternative to a flow meter for measuring flow if all that is needed is indication of flow beyond (above or below) a particular value.
RheoVac Multisensor Flow Monitor
The RheoVac family of instruments from Bionetics are unique multi-sensor flow meters that incorporate four primary measurements: flow, pressure, temperature, and humidity. Using these measurements and a sophisticated calculation engine, the probe is able to separate the air and water components of the flow and provide an air mass flow rate, water mass flow rate, humidity, dew point, partial pressure and other important process parameters.
The electronics transmitter provides these outputs to your control system over analog 4-20mA, Modbus or OPC protocols. The RheoVac probe is ideal for power plant condenser performance monitoring as well as industrial drying, evaporation monitoring, vacuum pump capacity monitoring and more.

Very Low-Pressure Drop: Thermal mass flow meters demonstrate negligible pressure drop, making them a leading choice for a wide range of pipe and duct sizes.
No Moving Parts: Thermal flow meters are easier and less costly to maintain than flow meters with moving parts and can easily be installed via hot tap.
Mass Flow Controllers/Meters
Over 80% of all industrial processes such as those involving chemical reactions, combustion, respiration, and HVAC are based on mass flow, not volumetric flow. Sierra Instruments’ Thermal Mass Flow Controllers are true digital MFCs based on thermal mass flow control technology that directly measures molecular flow by counting gas molecules.
Digital Mass Flow Meters are unaffected by upstream gas temperature and pressure fluctuations like other differential pressure devices. This feature allows them to provide the most reliable, repeatable, and accurate gas mass flow for various gases, including natural gas, air, nitrogen, and argon.
Key features of Sierra’s digital mass flow controllers include:
Accurate and repeatable flow measurement: Digital mass flow controllers measure down to the gas molecule, providing accurate and repeatable measurements.
Compact footprint: Sierra’s digital mass flow controllers offer the smallest footprint by flow range.
Multi-gas flexibility: Specify any gas, any flow range up to 1000 slpm (nlpm).

Vortex flow meters measure fluid velocity using a principle of operation referred to as the von Kármán effect. It states that when flow passes by an obstruction in the flow path, vortices are generated in a repeating pattern.
In a vortex flow meter, this obstruction is referred to as a bluff body. The bluff body causes the process fluid to separate and form areas of alternating differential pressure known as vortices around the backside of the bluff body. In Pro-V vortex flowmeters, a sensitive piezoelectric crystal sensor detects these vortices. The frequency at which the vortices are shed is directly proportional to the flow velocity. With the fluid velocity and area of the pipe known, a volumetric flow rate is calculated.
With optional integrated temperature and pressure sensors, Pro-V vortex flowmeters can provide a compensated mass flow rate. With the energy monitoring option, Pro-V meters can also provide a reliable (BTU) energy measurement of water, thermal oils, and steam. Insertion style vortex flowmeters are a more economical option on large line sizes and can be installed under full process conditions (hot tapping).
Pro-V® multivariable flowmeters utilize three primary sensing elements – a vortex shedding velocity sensor, an RTD temperature sensor, and a solid-state pressure transducer to measure the mass flow rate of gases, liquids and steam.
Systems that use external process measurements to calculate mass flow may not provide adequate compensation for the fact that process conditions can change radically between the point of velocity measurement and the point where upstream or downstream pressure and temperature measurements are being made. Because the Pro-V multivariable flowmeter measures all of these parameters in a single location, it delivers a more accurate process measurement.
Integrating multivariable output capability with a single line penetration also simplifies system complexity and helps reduce initial equipment cost, installation cost and maintenance costs.
