Thermal mass flowmeter

The Sage Prism™ is a battery-operated thermal mass flowmeter with data-logging capability. Designed to operate for up to 10 hours on a built-in rechargeable battery, the insertion-style portable thermal mass flowmeter can measure and log gas flows through existing ports in pipes 1 in. and larger. The meter has an automatic logging mode that captures flow data points every 10 seconds and a manual logging mode that captures flow data points each time the SEL button is pressed. Data, stored within the unit for subsequent uploading to a file, can be seen on a high-contrast graphical display. The meter displays the four-digit log number, flow rate, gas temperature, station and user identification, channel selection, graphical indication of flow, and time and date stamps.

Thermal dispersion flowmeter

The series TDMT thermal dispersion flowmeter is designed to be installed easily and nonintrusively into almost any pipe for flow sensing without obstruction. Completely encapsulated in epoxy resin, the compact, rugged, shock- and vibration-resistant meter features no moving parts and an adjustable measurement range with a minimum flow range of zero to 20 cm/s (zero to 0.66 ft/s) and a maximum flow range of zero to 4 m/s (zero to 13.12 ft/s). Its stainless steel construction (titanium option available) makes the meter resistant to aggressive media. The meter is compact in size and operates according to a new calorimetric principle, which provides a wide measurement range. Dwyer Instruments Inc. (Michigan City, Ind.).

Cavity pump

The Moyno® 2000 progressing cavity pump features a crowned-gear, universal-joint drive-train configuration that provides torque and thrust control. Designed to handle a range of applications from shear-sensitive chemicals to difficult-to-process slurries and sludges, the pump includes joint seals that protect gear joints from pumpage contamination. The gear joints are grease-lubricated to run at 180°F, cooler than oil-lubricated joints. The rear gear joint location in the pump reduces the radial load on the drive shaft and bearings and requires minimal pump disassembly to service. The line offers capacities of 0.5 to 568 m3/h (2 to 2500 gal/min) and pressure capabilities to 69 bar (1000 lb/in.2). Moyno Inc. (Springfield, Ohio).


Electromagnetic flowmeter

The TIDALFLUX electromagnetic flowmeter measures the volumetric flow rate of electrically conductive liquids in partially filled pipelines. Designed for accurate wastewater measurement, the flowmeter is suitable for industrial and municipal water and wastewater treatment applications. Featuring abrasion and chemical resistance, the flowmeters’ display of measured values is designed to be achieved regardless of rough product surfaces and distorted flow profiles. The meters provide a measuring error of less than 1% of the measured value, providing exact measurements with a low time constant, even in cases of wave motion and heavy contamination. Other features include quick response time, simple installation and commissioning, and low maintenance. KROHNE Inc. (Duisburg, Germany).


The TruBlue 575 Baro transducer measures and logs barometric pressure, as well as temperature. The nonsubmersible transducer has 8 MB of internal memory and stores up to 550,000 data points. With an internal 3.6-V lithium battery, onboard surge protection, and a life span of 5 years, the system is suitable for groundwater and surface water data collection and monitoring applications in low-maintenance systems and remote locations. The 0.75-in.-diameter transducer comes with TruWare software created specifically for the TruBlue line that enables users to view, graph, and export test data. The system comes in stainless steel or titanium and has an operating temperature range of zero to 50°C. Pressure Systems Inc. (Hampton, Va.).
