Low flow measurement and control is a difficult application. Ultra low flow mass flow controllers can accurately control flows from 0.1 to 0.4 sccm which is ideal for measuring and controlling doping gases for pilot plants and other research houses.
Whether you are a researcher or an operator working with wastewater treatment processes, it is crucial to have access to highly accurate and precise data to get insight into the wastewater treatment processes.
If you are working in R&D on animal feed, diet formulation, nutrients or supplements for ruminants, you can rely on Gas Endeavour to provide accurate & precise volumetric gas production measurements for various in vitro digestibility test.
Sierra is an expert in the control of high flows of gases. With our large and powerful control valves and PID valve control, Sierra`s mass flow controllers, with industry-best low pressure drop, can control much higher flows than equivalent flow controllers with minimal pressure drop requirements.
With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to...
The Township of South Glengarry installs a new Greyline AVFM 5.0 Area-Velocity Flow Meter to measure continuous discharge from their municipal sewage lagoon. The sealed ultrasonic sensor is mounted in a horizontal 12` PVC pipe. The AVFM replaced a magnetic flowmeter that was unable to measure seasonal low flow rates.
The Environics Series Continuous Emissions Monitoring Calibration Systems (CEMCS) have been used in CEM vans and laboratories for over twenty years. They meet or exceed the performance requirements of the United States EPA 40 CFR Part 51 Method 205 Appendix M.
Our systems are custom built, computerized, mass flow controller based gas calibration systems which allow you to dilute a single high concentration cylinder of span gas to low levels for the calibration of gas analyzers.
Soil density, hardness, lithology, and sediment particle size distribution can create slurry of variable makeup and density. At a constant pump speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sand outs in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flow meters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent,...
The TD-4100 utilizes a non-fouling, non-contact flow cell which requires little to no maintenance, and uses fluorescence technology to accurately detect oil in water from low ppb to high ppm. For this application, the TD-4100 monitors oil in water at 1 to 5 ppm and signals an operator with an alarm when the concentration exceeds the high alarm relay set-point.
Specialized data loggers for connection with flow meters, rain gauges, water level sensors, and weather stations. Designed for fast deployment at a low cost, these standalone solutions are weather-resistant for reliable operation under hostile conditions. Our real-time telemetry and early warning systems include GPRS data loggers to monitor remote sites.
Security of water assets is becoming an increasingly major issue that demands immediate and robust alarms for potential contamination. In addition to this, natural growth of algae is a common problem for water asset managers, the results of which can increase maintenance costs of water processing plants as well as directly effecting water taste. The CTG FastGuard fast repetition rate fluorometer analyses information on the physiological state of the algae it monitors within an in-line flow system. A number of...
