1.2 About the transmitter

Micro Motion sensors and transmitters with enhanced EMI immunity

comply with EMC directive 89/336/EEC and low-voltage directive

73/23/EEC, when properly installed in accordance with the guidelines

and instructions in this manual.

The Model RFT9739 transmitter is a microprocessor-based transmitter

for fluid process measurement. The transmitter works with Micro Motion

sensors to measure mass or volume flow, density, and temperature.

An optional display is available, and comes installed on the removable

housing cover. Scroll and Reset knobs on the cover enable the user to

perform the following operations (see

Section 6.2

, page 51):

• View flow rate, density, temperature, mass and volume totals and

inventory levels, and status messages

• Set the transmitter's flow totalizers

• Reset communication parameters

• Zero the flowmeter
