Variable area flow-meter Spirax Sarco

The Spirax Sarco DIVA pipeline unit is a complete flowmetering
system. It provides a fully density compensated 4-20 mA output
proportional to mass flow as well as a digital pulsed output. The
system comprises of:
The DIVA pipeline unit. This is installed in the line where the flow is
to be measured. There is no requirement for impulse lines or
additional equipment. The DIVA measures the force caused by the
deflection of a precision made cone due to the flowrate and converts
it to a 4 - 20 mA and digital pulsed output signal proportional to mass
flow. This output signal can be used in a number of ways
