300-R010-45L Datasheet, PDF (1/12 Pages) Magnetrol International, Inc. – Echotel® Model 300/301 Ultrasonic Non-Contact Transmitter For Level, Volume, and Open Channel Flow
Echotel® Model 300/301
Ultrasonic Non-Contact
Transmitter For Level, Volume,
and Open Channel Flow
DESCRIPTION
The Model 300/301 is a full-featured, powerful ultra-
sonic system for measurement of liquid level, volume,
or open channel flow. Available as an integral or
remote mounted transmitter, this extremely versatile
system is simple to install and calibrate. The non-
contact design means that it is not affected by changes
in specific gravity, viscosity, or conductivity.
FEATURES
• Isolated 4–20 mA output includes an active/passive
mode for loop power or device power.
• RS-485 with Modbus protocol allows bi-directional
communication with DCS or PLC.
• Two or four 10 amp SPDT gold flash relays provide
flexibility for most alarm and control schemes.
• 16-button keypad and two-line, 16-character LCD
alphanumeric display.
• Temperature compensation integral to ultrasonic
transducer.
• Output in units of level, volume, or open channel
flow.
• Most common flumes and weirs preprogrammed in
memory in addition to the Manning formula and a
custom table using either a linear or spline curve.
• Complete self-diagnostics checks all relays, outputs,
and system functionality.
• Class I, Div. 1, Groups B, C, and D on both the
transmitter and transducer.
• QuickCal mode allows complete system calibration
in 90 seconds.
• Powerful 38 kHz EchoMaster™ ultrasonic transducer
performs in difficult applications.
• Password protection prevents unwanted tampering
with configuration data.
APPLICATIONS
• Water and wastewater
• Slurries
• Viscous fluids
• Acids
• Oils
• Caustics
