(t).jpg) | QuadraTherm™ 640i / 780i World's Highest Performance Thermal Mass Flowmeter QuadraTherm introduces the first four-sensor thermal mass flow meter design—three precision platinum temperature sensors and one patented DrySense mass velocity sensor backed by a lifetime warranty. The flow meter is available in aninsertion version and an inline version. Impossible to achieve with a traditional two-sensor design, the four-sensor QuadraTherm measures all thermal heat transfers occurring and works in harmony with our proprietary iTherm algorithm set to solve the First Law of Thermodynamics (for thermal dispersion technology) in a fraction of a second for each mass flow data point. The instrument measures, then calculates stem conduction and all other unwanted heat loss components, subtracts them out, and then computes gas mass flow rate from the remaining forced convection (gas mass flow) component. iTherm is also the "Brain" behind the flowmeter's capability to change gas (Dial-A-Gas) and pipe size (Dial-A-Pipe) in the field, while also allowing gas updates to the instrument via the internet which connects to the most up-to-date gases in our proprietary iTherm Gas Library. The QuadraTherm 780i inline version achieves accuracy of +/- 0.5% of reading making it the most accurate thermal meter in the world. Before now, this level of accuracy was never thought possible with thermal dispersion mass flow meters. Inventor of the technology, Dr. John G. Olin, explains the challenge. Watch the video...

.jpg) | Innova-Mass® Model 240 VTP (Multivariable Mass Vortex) In-line Multivariable Mass Vortex Flow Meter Read five process variables with a single installed device! Our award-winning Innova-Mass® Model 240 can measure the mass flow rate of any gas or liquid and are ideally suited for saturated or superheated steam. Our multivariable Technology allows one instrument and one process connection to measure FIVE process parameters at the same time to simultaneously measure mass flow rate, temperature, pressure, volumetric flow rate, and fluid density. The Innova-Mass cryogenic version has undergone extensive testing and field validation over the last several years proving that the meter is preferred versus traditional turbine meters for measuring mass flow rates of cryogenic fluids down to -328°F (-200°C). Using a special cryogenic temperature RTD, mass calculations are done with the latest density equations of state for liquid Oxygen, Nitrogen, Argon, and CO2. The Model 240 is fully field-programmable, configurable and feature RS485, MODBUS or HART protocols. Additional Info: http://www.sierrainstruments.com/products/liquidflowmeters.html  | ||||||||
.jpg) | Multi-Trak™ Model 670S Large Duct and Stack High-Performance Multi-Point Mass Flow Sierra's Multi-Trak™ Model 670S is an advanced state-of-the-art instrument for measuring mass flow rates in very large ducts or stacks that have non-uniform velocity profiles, high turn-down requirements, dirty gas streams, wide temperature ranges and fast velocity and temperature changes. The Multi-Trak™ dynamically compensates for changes in the flow profile by using up to four independent mass flow sensing points to measure the instantaneous average gas mass flow velocity. The Multi-Trak™ is commonly used in petrochemical refining, coal-fired electric power generation, steel manufacturing and many other industrial processes that face the challenge of accurate and repeatable gas mass flow measurement in very large pipes or ducts. An innovative, versatile and user-friendly microprocessor-based Human Machine Interface (HMI) controls all functions of the Multi-Trak™system. The HMI is used to collect, visualize and store flow data, as well as set up the individual sensor points, thus allowing the entire system to be easily configured in the field. The Multi-Trak™ HMI integrates the functions of flow measurement, flow-range adjustment, field validation and diagnostics, and displays mass flow rate and totalized flow, as well as other configuration variables. All of this data is easily programmable from the HMI's easy-to-use touch screen. Unlike single probe insertion sensors where each sensor point is on the same insertion probe, each Multi-Trak™ sensor point is completely independent of the others, allowing for easy field swap-out or cleaning of individual transmitters.

Steel-Mass Air Flow Meters are GHG Certified As a certified greenhouse gas (GHG) air flow meter, the Steel-Mass:
Steel-Mass is also a popular choice forlandfill gas(LFG) measurement applications. LFG – a very humid, dirty gas that leaves the landfill at low pressure (20 - 40 mBarg) and about 40-60°C (100F) – makes differential pressure (DP) devices like orifice plates unsuitable, while variable flows require a large turndown. Sierra's Model 640S Insertion Mass Flow Meter is ideal for LFG, as it offers 100:1 turndown, has no moving parts and generates nominal pressure drop across the immersible sensor probe.

.jpg) | InnovaMass® Cryogenic Accurate Liquefield Gas Measurement Our customers needed an advanced and more reliable measurement system to accurately measure the delivery of cryogenic gas to the rapidly growing liquefied gas market. The volumetric turbine meters traditionally used could not meet the accuracy requirements of a mass flow device. Lower accuracy meant under billing and lost revenue. As a result, a cryogenic version of the InnovaMass® 240 multivariable mass vortex flow meter was developed as an ideal solution for this challenging application. The instrument has undergone extensive testing and field validation over several years on cryogenic gas delivery trucks proving to be preferred versus traditional turbine meters. The 240 cryogenic version measures the mass flow rate of cryogenic fluid down to -330°F (-200°C). Using a special cryogenic temperature RTD, mass calculations are done with the latest density equations of state for liquid oxygen, nitrogen, argon, and carbon dioxide. The 240 excelled in accuracy performance and has the added benefit of no moving parts to wear out or be serviced like a turbine meter. Customers now get a more reliable, stable reading and an increased service life. Unique Product Features:
