Grooved style main orifice carriers are available, suitable for use with standard clamp style connectors. Alternative materials of construction are available, including all 316 ss and plastic construction. Remote siting of the indicator, up to 10 metres from the main orifice carrier can be accommodated

using flexible nylon tube.

The indicator can be fitted with a high, low or dual infrared alarm Customised flows for specific operating conditions. Additional Sizes and ranges are available on request

flowmeter is a function of installation. For

best results, minimum straight lengths of

pipe 10 diameter upstream and 5 diameter
