SmartPD Meter
Brand: Niagara Meters
The SmartPD meter is a volumetric meter that provides total volume and flow rate measurements by way of an electronic transmitter.
This 2-wire device provides an Analog response by way of a 4-20 mA signal, digital feedback via HART communication, and a visual indication of change on an LCD.
There are two variations of this meter; the SmartPD nutating disc (SND) and the SmartPD oscillating piston (SOP).
The SmartPD meter measures volume and flow rate for a wide range of materials.
The space-saving design eliminates the need for upstream and downstream pipe requirements, and it is offered in a wide range of materials, finishes and line sizes.
