1.6 About the transmitter
The SmartLine Wireless Transmitter is furnished with an ISA100.11a-compliant wireless
interface to operate in a compatible distributed ISA100.11a wireless system. The transmitter will
interoperate with any ISA100.11a wireless network.
The transmitter includes ISA100.11a-compliant electronics for operating in a 2.4 GHz wireless
network. It features function block architecture and instantiable input channels.
The SmartLine Wireless Transmitter comes in a variety of models for measurement applications
involving one of these basic types of pressure:

Differential pressure

Gauge pressure

Absolute pressure
The transmitter measures the process pressure and transmits the measured value as a digital
output signal in user-configured engineering units. Its major components are an electronics
housing and a meter body as shown in
transmitter).
The SmartLine Wireless transmits its output in a digital OneWireless protocol format for direct
digital communications with systems.
The Process Variable (PV) is available for monitoring and alarm purposes. Available PV update
rates: 0.5, 1, 5, 10, 30 seconds, 1, 5, 15, 30 minutes and 1 hour are set on the OneWireless User
Interface. Slower update rates extend battery life. The meter body temperature is also available as
a secondary variable for monitoring.
Wireless Transmitter's operating functions.
The SmartLine Wireless DP model type is capable of measuring mass flow and volumetric flow.
When minimum and maximum flow rate values are configured as PV scale 0% and 100% values
at given PV units of measure, and the respective DP values at those limits are configured as the
calibration scale 0% and 100% values, the PV value becomes a flow rate in the selected units of
measure. Minimum and maximum flow rate data at given DP values is either provided on or
with orifice plates, or is commonly available according to orifice plate size.
