7ML1118-0BA30 Ultrasonic Level Transmitter for Sludge Interface Instrument Applications: The MultiRanger can measure various media, including fuel oil, municipal wastewater, acids, alkalis, or other corrosive and toxic substances. The MultiRanger provides dual-point level measurement with a built-in Modbus® RTU RS-485 digital communication interface. The SIMATIC PDM software can be used to configure and set the device on a PC. The intelligent echo processing software enhances measurement reliability.

MultiRanger 100 provides level alarms, on/off control, and pump control, making it an economical solution.

MultiRanger 200 can monitor open-channel flow, relay alarms, pump control, and volume conversion functionality. It works with the corrosion-resistant Echomax ultrasonic sensors and can be used in demanding applications, with an operating temperature up to 145°C.

Main Applications: Well water, water tanks, weir and grid control, chemical storage tanks, and liquid storage tanks.

Design: MultiRanger is available in wall-mounted and panel-mounted options.

Echomax XPS Ultrasonic Sensor Applications:
Echomax ultrasonic technology monitors liquid and slurry level variations, with a wide range of applications.

Product Features:

Built-in temperature compensation

Low residual vibration technology ensures a small blind zone

Acoustic impedance matching technology is used for applications involving slight dust

Self-cleaning and low maintenance cost

Resistant to chemical corrosion

Integrated design ensures air-tightness

Applications: The sensor can be installed inside process vessels, suitable for applications with steam and harsh chemical corrosion, and can be installed without flanges.

The XPS series has a monitoring range of up to 30 meters, with an operating temperature up to 95°C. During operation, the Echomax ultrasonic sensor emits sound pulses with a narrow beam vertically to its surface. The level transmitter calculates the distance by measuring the time difference between the transmitted pulse and its echo.

Siemens Sludge Interface Instrument includes: transmitter, sensor, mounting bracket, and handheld controller.
