This innovative design provides a high accuracy, non-invasive, flow measurement

device at a fraction of the cost of other current non-invasive systems. The unique

measurement technique automatically compensates for viscosity and temperature

variations. The measurement of flow is by ultrasonic transit time in-line cell.

The flow path is designed to minimise pressure drop and, having no moving parts

within, will not clog or jam. The sensor also allows contaminants to pass through

without affecting its performance.

The sensor is supplied with pulse and analogue outputs, which are selectable by

connection wires..
