100 Series Secondary Instruments

The 100 series of secondary instruments have been designed as a rugged and versatile range offering the user anything from simple flowrate indication to batching, ratio metering and controlling applications. The indicator can be head, wall or panel mounted and the standard aluminium case design is to IP67.

A large LCD dual display shows clear text and measuring units. The units are battery powered as standard and the easily replaced lithium battery has an average life of seven years.

A scaleable pulse and analogue output is available as standard. The units are very easy to program and the whole range have been designed with the same clear logical menu structure.
