Ultrasonic Flow Meter UF25B
cynergy
components
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..
