ZM4 Instruction Manual 9R87-B June 2012

Applications (continued)

If you are using a DN or DI (Differential Pressure Sensor) the high pressure

port (P1) is teed into the pressure source and transmitter high side (H) and

low pressure port is vented to atmosphere. If you are using a GI or CI

(Gauge Sensor) there is only one pressure connection.

In addition to reading gauge pressure the M4 can also be used to measure

pressure drop across a pressurized system. Examples include orifice plates,

pitot tubes, filters, or valves. A push to read, three valve, or five valve

manifold is recommended to avoid damage to the sensor.
