S-93--E
2. OPERATING CONDITIONS
The monitor operating conditions are stated on the specification label, Section "INSTALLATION" and Section
9 "GENERAL SPECIFICATIONS." Read carefully before initiating operation.
CAUTION:
This monitor is of non-explosionproof configuration; it is not serviceable in a
hazardous location.
3. GENERAL
This monitor is a small, lightweight flowmeter, using a
heat-sensitive resistance element.
Of the two heat-sensitive resistance elements located
perpendicular to the fluid flow; one detects the fluid
temperature and the other, which plays the role of
a heater, regulates the temperature of the former to
maintain a constant temperature differential. As the
flowing process fluid (mass flow) dissipates heat
from the latter which serves as a heater, its supply
power increases in order to maintain the temperature
differential. This change in power consumption (voltage
and current) is used to calculate the mass flowrate.
3.1 Features
() Absence of moving parts contributes to long life.
() Major components are made of synthetic resin. Lightweight and compact.
(3) Sturdy metallic couplings.
() The display is a backlit LCD for readability in darkness.
() May be installed in any position. The display can be oriented in 90 deg steps to see easily.
CAUTION:
Adjusting the display orientation requires opening the upper case of transmitter.
The procedure to change orientation appears in Section 5.3 "How to Change
Display Orientation".
