Velocity Interface Pulsar Wall-mounted Velocity Measurement Controller

The Velocity Interface has been designed to provide a simple interface with the MicroFlow and Speedy Velocity Sensors.

Housed in an IP67/Nema 6 enclosure the product is ideally suited to applications where velocity monitoring, reporting or control is required.

Pulsar’s Speedy Interface is a digital to analogue converter that works with the latest Speedy velocity sensor in two important ways. It frees up the RS485 output from a FlowCERT controller in applications where digital communications are required, and allows users of Pulsar's older equipment to upgrade to the latest Speedy sensor. It also provides the option of alarms based on flow velocity.

The Velocity Interface controller is very easy to use and may be calibrated quickly and simply via the on-board keypad and display, or alternatively by using the optional handheld calibrator, which connects to the unit via the RS232 interface and provides an on-board LCD display.
