Measuring level is important in any process application to gather data and prevent overfill or underfill which will affect the manufacturing production and to avoid unplanned shutdowns.

Although it is important to determine whether you will be measuring fluid or solids it is also important to decide whether you require single point switching control or continuous data with control output. Parmley Graham portfolio has the solution for your process instrumentation system.

Whatever your requirements may be, the process instrumentation team at Parmley Graham are here to help you find the exact product you need from our wide range of partner suppliers.

Siemens SITRANS LR100

Siemens Point level technology covers it all, capacitance, ultrasonic, rotating paddle and vibrating fork level switches which are suitable for virtually all applications from bulk solids to liquids, and everything in between.

Siemens continuous level measurement, featuring a full range of technologies for your exact application: ultrasonic, radar, guided wave radar, capacitance, gravimetric and hydrostatic.

New for 2021 is the SITRANS LR100 series of 80GHz radar transmitters for reliable and Bluetooth-enabled level measurement. These sensors help to accommodate for signal killers (such as condensation, turbulence and dust) and are easily set up via their exclusive mobile app, the SITRANS mobile IQ app. For more information on the LR100 series, see our news article, or view the video below.

Kobold Messring

Float switches from Kobold Messring work extremely reliably within a defined tolerance range. Level indicators and level sensors can be adapted to a wide range of liquids and environments, including environments with heavily polluted fluids. With a wide selection of materials available for level sensors and level switches, level measurement is possible in many applications.

Georg Fischer

Georg Fischer Piping Systems (GF) offer a wide range of Level measurement instruments designed for almost all applications, particularly where corrosion is an issue.

GF Piping Systems offers a carefully selected range of point level switches. Different application conditions require dedicated working principles, such as vibrating level forks, float switches and conductive level switches specific process connections and wetted materials of excellent quality. GF Piping Systems point level switches ensure safety in your industrial tank applications.

Georg Fischer provides high-end continuous level sensors whose range include hydrostatic level sensors, radar sensors, ultrasonic sensors for level measurement in tanks containing heavily agitated liquids or dense foam layers or chemical fumes. These are a good choice in terms of performance, reliability and durability they provide superior chemical compatibility.
