Keller Series DCX-22 CTD level data loggers

29 July, 2014

With the CTD (conductivity, temperature, depth) versions of the high-precision DCX level data loggers for depths of up to 200 m, Keller offers an integrated pressure measurement solution for water management. The data logger for long-term monitoring stores over 50,000 time-stamped level measurements, as well as the associated conductivity and temperature readings.

Keller DCX data loggers for hydrostatic level measurements

28 July, 2014

Keller offers probes to monitor groundwater levels and filling levels in tanks that can be used under a wide range of conditions. The probes provide fully autonomous operation or they can be used with an integrated data logger, wireless transmission (GSM), ambient pressure-compensating capillary or a separate absolute pressure sensor.

Keller titanium pressure transmitters and pressure sensors

27 July, 2014

Keller offers titanium versions of its products for use in heavily corrosive media. The company has developed an implantable sensor made of titanium, offering a host of advantages for applications under special conditions.

KELLER LEO 1 digital pressure peak gauge

26 July, 2014

KELLER has released the LEO 1, a microprocessor-controlled digital pressure peak gauge which polls the value for the pressure variable in a process 5000 times each second. This results in detection of short pressure peaks, usually caused by fast-switching hydraulic valves and pump units, and means action can be taken to prevent damage.

Keller Series PRD-33 X differential pressure transmitter with double sensor

25 July, 2014

Keller is launching the Series PRD-33 X, a differential pressure transmitter suitable for measuring the levels in liquefied gas tanks safely. The product has two independent sensors and measures the line pressure as well as the differential pressure.

Keller Series 4 LD digital combination transmitter

24 July, 2014

Keller has launched a fully functional digital combination transmitter for pressure and temperature. In the LD series, all the electronic components are accommodated in a laser-welded stainless steel housing filled with silicone oil.

Keller Series 4 LC...9 LC pressure transmitters

23 July, 2014

The Keller Series 4 LC to 9 LC pressure transmitters offer two output signals: a ratiometric analog voltage output and a digital inter-integrated circuit interface (I2C). The ratiometric signal eliminates the need for a voltage reference in the support electronics to the A/D converter.

11 July, 2014

The Hach DR1900 is a light and compact portable spectrophotometer that has been designed for accurate field testing.

Red Lion PXU PID controller series

09 July, 2014

Red Lion Controls has announced the PXU series of proportional-integral-derivative (PID) controllers. The series is designed for machine builders, systems integrators and commercial equipment manufacturers.

Simple sensor for detecting oestrogen in the environment

04 July, 2014

Researchers from Victoria University of Wellington have developed a technique that can detect minute levels of oestrogenic hormones - molecules with the potential to affect human and animal reproductive cycles - in the environment.

Dwyer Instruments Series UFB Ultrasonic Flow Meter

30 June, 2014

The Series UFB Ultrasonic Flow Meter Set uses the transit-time difference for measuring flow rates in pipes non-invasively. The permanent model allows the user to mount the converter on a surface or pipe.

Emerson Rosemount 5300 Guided Wave Radar (GWR) level transmitters

20 June, 2014

Emerson's Rosemount 5300 Guided Wave Radar (GWR) level transmitters are certified to IEC 61508 for safety instrumented functions up to SIL 3. Companies in the oil and gas production, refining, petrochemical, chemical and power industries can benefit from the accuracy and flexibility of the series for safety-critical level applications such as overfill prevention and dry pump protection.

Unitywater extends network monitoring contract with TaKaDu

16 June, 2014

Queensland water utility Unitywater has extended its contract with TaKaDu, an integrated water network management company. An initial 12-month trial provided Unitywater with a smart water network monitoring service designed to find hidden leaks and identify service abnormalities.

Grundfos Demand Driven Distribution pressure management system

03 June, 2014

Demand Driven Distribution is a pressure management system that combines precise measurement of the network pressure and pump control at the pumping station according to these measurements. This avoids the issues that can arise with other systems that use, eg, pressure reducing valves.
