4 / 8 page 4 NON-CONTACT ULTRASOUND 300/301 ForLiquidLevel, Volume or Open Channel Flow Available as an integral or remote mounted unit, this versatile and powerful ultrasonic transmitter is easy to install and quick to calibrate. Advanced Electronics Isolated 4–20 mA output with 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 for a wide variety of alarm and control schemes. Explosion-Proof Transmitter and Transducer The Model 300/301 has Explosion-Proof FM and CSA agency approvals for both the transducer and the trans- mitter: Class I , Division 1, Groups B, C, and D. Fast, Password-Protected Calibration Unique QuickCal™ calibration feature allows complete system calibration in 90 seconds. A password protection feature also prevents unwanted tampering with the configuration data.
