The 328FM is a loop-powered flow totalizer used in conjuction with a level transmitter or flowrate transmitter to calculate total flow in an open channel.
The unit recieves a 4-20 mA signal that is either proportional to the liquid level in the channel, or that is proportional to the flow rate in the channel. The unit calculates the flow from the input signal and displays the total flow in user selectable units of measure.
The Delta Controls Model 658 is an ultrasonic open channel flow computer featuring totalization, sampler control, 4-20 flow rate output, and alarm relays.
The Delta Controls Model 668 is like the 658, but takes its input from any 4-20mA level sensor. The normal sensor is a series 500 head pressure type.
