Solartron Mobrey has extended its range of vibrating fork density and viscosity meters with a series of long-stemmed versions, ideal for top-mounted, direct-insertion into storage, mixing and process tanks.

With no need for side access or a sample loop, the new products allow cost effective, accurate density measurement in a wide range of traditionally demanding, difficult to measure applications.

The microprocessor-based meters use the Solartron Mobrey market-leading vibrating fork technology to measure the density and viscosity of the liquid.

They are suitable for monitoring and control duties with liquids in the density range 0-3000 kg/m3 and viscosity range 0.5 to 20,000cst.

Applications are wide and varied; examples include interface detection in static tanks, paint mix control and fermentation monitoring.

The new meters, available with long-stemmed forks up to 4.0 metres are ideal for top-mounting in jacketed, buried or other difficult-to-access tanks.

They can be used in both open and closed tanks, and even in process tanks which have stirrers or agitators, to provide a reliable density and/or viscosity measurement where other technologies (such as differential pressure for example) fail.

Like the others in the range, the new products incorporate advanced electronics which carry out all signal processing and calculation.

Output is a 4-20mA signal and via an RS232/485 Modbus interface for continuous monitoring of multiple parameters.

Meters can be used for stand-alone monitoring, or with the Solartron Mobrey AdView software for PC-based remote configuration, diagnostics, data logging and analysis, or integrated into any plant-wide computerised control or SCADA system.

All the long-stemmed meters are 316 stainless steel sealed to IP66, and are ATEX and hazardous area approved to EExd IIC T4.

They can be supplied with electro-polished or PTFE-coated tines to provide non-stick self-cleaning properties.
