KROHNE MESSTECHNIK GMBH

Conductivity sensor for water Analysis The conductivity sensors of the OPTISENS COND 1200 series have a standardized robust design and a long lifespan. The conductive measurement principle is characterized by high sensitivity, especially at low conductivity values. For this reason, the COND 1200 sensors are perfect for low-contaminated, noncorrosive media such as pure water, steam and cooling water.

The OPTIBAR DP 7060 is a differential pressure transmitter with integrated absolute pressure measurement. It offers a high degree of modularity for various flow, hydrostatic level or process pressure applications. For DP flow measurements it can be perfectly combined with the KROHNE primary elements (e.g. orifice plates or pitot tubes). Featuring a quick response time of just 125 ms, the DP transmitter offers high accuracy and measurement stability under all process conditions. KROHNE is the only manufacturer of process instrumentation to carry out a total 3D linearization of its differential pressure transmitter. For a robust and accurate differential pressure measurement, even under changing process conditions, each OPTIBAR DP 7060 differential pressure transmitter is linearized in all three dimensions during calibration: differential pressure, ambient temperature and static pressure are taken into account in combination.

The OPTIBAR PC 5060 is a pressure transmitter for process pressure and hydrostatic level measurement in all kinds of process applications. It is designed for absolute and gauge pressure measurement in open tanks and – as dual version for electronic differential pressure measurement – also in closed vessels. The pressure device features a ceramic capacitive measuring cell that guarantees maximum overload and vacuum resistance for high plant availability. The measuring cell can be built into the process absolutely flush and the radially recessed position of the gasket provides additional protection in abrasive media. It is resistant to sudden temperature shocks and can handle operating temperatures of up to +150°C/ +302°F. The OPTIBAR PC 5060 comes with robust plastic and aluminium housing or hygienic stainless steel versions (incl. ingress protection IP69k). The pressure transmitter comes with various diagnostics and digital communication options.

The DK46/47/48/800 is a variable area (VA) flowmeter for monitoring and adjusting extremely small flow rates of liquids and gases. It is thus particularly useful for sample flow monitoring in analyser systems and gas chromatographs or measuring liquids and gases in laboratories and pilot installations. The purgemeter operates without auxiliary power supply and is available with different glass tube and installation lengths from 90 to 325 mm / 3.55 to 12.8". The medium is visible and the flow value can be read directly off the scale at the height of the float. The glass flowmeter can be provided with max. two limit switches (NAMUR) or a 3-wire digital output. For precise setting of the flow value, the VA meter features a needle valve. The DK 46/47/48/800 is also available with a differential pressure/flow regulator to provide constant flow rates in case of varying inlet or outlet pressures. The device has approvals for use in hazardous areas.

The H250 M40 is the standard variable area (VA) flowmeter for the process and OEM industry. The VA meter combines mechanical flow measurement of liquids or gases with state-of-the-art communication capabilities. Additional electronic modules can be added or replaced at any time without process interruption. The H250 M40 is available in various materials and in many different versions. The sturdy all-metal flowmeter can be also used in applications with high pressures (up to 1000 barg / 14500 psig), temperatures (-196...+400°C / -320...+752°F) or aggressive media. It even allows installation in horizontal or fall pipes up to DN150 / 6". A special version for use in hygienic applications is also available. The H250 M40 is intrinsically safe and explosion-proof. Certain variants of the flowmeter with limit switch or analogue output are suitable for use in Safety Instrumented Systems (SIS).

Battery powered electromagnetic flowmeter for drinking water applications WATERFLUX 3070 is the first battery powered water meter for the drinking water industry that is capable of measuring flow, pressure and temperature with one sensor. To enable remote access to flow, pressure and temperature data the WATERFLUX 3070 has a RS485 Modbus RTU communication option. For this it has a special Modbus version designed for battery operation. With its real-time-data on flow, pressure and temperature the WATERFLUX 3070 provides important data to support customers business processes like zoning for water balance (DMA), water abstraction, pressure management, and revenue collection.
