Analysts say flowmeter sales are growing

Ultrasonic Volumetric Flowmeter
System 1010PV has embedded compensation software that allows it to make volumetric flow measurements in applications previously requiring the use of mass meters. Based on the unique and definable relationship between the sonic characteristics of a liquid and its temperature, the meter compensates for the impact of viscosity on Reynolds Number, producing a gross volumetric flow rate independent of viscosity. Compensated volumetric flow is displayed and output in RS232, pulse rate, 0-10 V and 4-20 mADC formats. Controlotron  

Enhanced Coriolis
Enhancements to the Quantim Coriolis mass flow meter/controller includes a valve that is more forgiving of variations in line pressures and reduces the chance of clogging. The valve also uses an all-metal valve seat, thus eliminating potential control issues associated with elastomer valve seat compatibility and swelling. The meter measures flow of liquids and gases in ranges from 1 to 28,000 g/hr, and is approved for use in Class 1 Division 2 installations as a UL-recognized component. Brooks Instrument/Emerson   

Cool Flowmeter
Coolpoint vortex shedding flowmeter measures and totalizes flows of water and low viscosity fluids such as water-based machine coolant and water/glycol mixtures. It has a scaled pulse output, 2% accuracy, and repeatability of 1%. Meters are available in sizes from 1/4 to 2 in., for flow rates from four-tenths of a gallon per minute to 200 gpm. Prices start at $350. Universal Flow Monitors        

Mass Flow Meter for Natural Gas
Thermal mass flow meter measures mass flow directly, compensates for process temperature changes, and can be configured to track gas usage and assess when peaks occur. Meters can be installed in burner lines to measure gas and oxygen flow for combustion control. The meters have no moving parts and are insensitive to dirt. Sage Metering 

Flow Tubes
Flo-Tube flow sensors create and sense a pressure difference in flowing media within a pipeline or any other closed conduit. When connected to the appropriate secondary instrumentation, such as a differential pressure gauge or 4-20 mA transmitter, it provides flow measurement data with 1% accuracy and 0.1% repeatability. Options include single, double and hot tap mountings, integral RTD and PTM;  and customized units for existing mountings. J-TEC Associates      

Flow Transmitter Checks Depth
The DVF-320 Depth Velocity flow transmitter has a submerged depth sensor with vented cable for level measurements. It measures flow rate, liquid level, and velocity. Applications include monitoring sanitary sewers, infiltration inflow, billing, sewer capacity, storm sewers, lift stations, influent/effluent, and as a disinfection system control. The sample rate may be adjusted to record depth, velocity,flow or average flow rate once every 10 seconds to once a day. Scientific Technologies 

Mass Flow Controller
The Model CMQ thermal flow sensor is capable of 1 mm/sec resolution and 2 msec response time. It is unaffected by temperature and/or pressure changes, and can measure reverse flow. Yamatake    

Piston Style Flow Meter
The Model 214 is rated for 7,500 psi, making it suitable for leakage testing on hydraulic test stands. It has  0.5% linearity over a 1000:1 range and a bottom end flow rate of 3 cc/min. The meter can be combined with a photo-optic or RVDT frequency transmitter to provide up to 100 pulses per cc. Options include analog transmitters with voltage or current outputs. Max Machinery     

Thermal Mass Flow
Series 534FT in-line thermal mass flow transmitters include eight models covering the mass flow range of 0 to 2350 SCFM, in pipe sizes from 1/2 to 8 in. The instrument uses flow nozzles and flow diffusers to obtain flow disturbance immunity without the need for screens, honeycomb or vortex generators at a low end-to-end pressure drop. All models have hazardous gas approvals, and CE compliance. Kurz Instruments
