Instrumentation products give engineers visibility of what is happening inside their pipelines and process systems — pressure, temperature, flow, viscosity, density, and liquid level. Just Valves supplies mechanical instruments for local indication and electronic transmitters for control system integration, as well as sight flow glasses for direct visual confirmation of flow and fluid clarity.
Just Valves supplies a comprehensive range of pressure and temperature instrumentation for process, industrial, and OEM applications. The range covers mechanical pressure gauges, dial thermometers, pressure transmitters, temperature transmitters, RTDs and thermocouples, thermowell assemblies, viscosity transmitters, industrial densitometers, and data acquisition systems. Instruments are available as individual items or complete measurement systems with displays, recorders, and calibration equipment.
Mechanical pressure gauges use a Bourdon tube, diaphragm, capsule, or bellows element that deforms under pressure, translating into dial indication. Pressure transmitters convert pressure into a 4-20mA or digital signal for control systems. Temperature measurement uses bimetallic dial thermometers for local indication, or RTDs and thermocouples with transmitters for remote signal output. Thermowell assemblies protect the temperature sensor from process media while allowing easy replacement without process shutdown.
Just Valves supplies a comprehensive range of flow indicators and sight glasses for visual confirmation of flow, clarity, and liquid level in pipelines and vessels. The JV range is designed for safe use with extremely corrosive and ultra-pure liquids including sulphuric acid, hydrochloric acid, chlorine, caustics, and demineralised water. Double-wall Pyrex-and-acrylic construction provides maximum chemical resistance with impact protection. All indicators are full-ported to eliminate flow restriction and provide 360-degree visibility for observation from any direction.
A sight flow glass is installed in a pipeline to give direct visual observation of the process fluid inside. The Pyrex glass inner wall provides chemical resistance while the high-impact acrylic outer wall acts as an armour shield. A hinged stainless steel vane indicator confirms flow presence and direction. Full-bore design ensures no flow restriction. Optional mechanical flutter devices indicate the presence of flow that would otherwise be difficult to observe at low flow rates.
