Product catalog summary
Overview: The document provides detailed specifications and operational guidelines for the OCM F flow meter, designed for measuring flow in partially filled and full pipes, channels, and flumes. It is suitable for various applications including wastewater treatment, industrial flow measurements, and irrigation systems.
Specifications: The OCM F operates on a power supply of 100 to 240 V AC or 24 V DC, with a power consumption of 18 VA. It features a polycarbonate wall mount enclosure with IP 65 protection and an optional Ex approval for hazardous areas. The operating temperature ranges from -20°C to +60°C, with a storage temperature of -30°C to +70°C. The device includes a back-lit LCD display and a 6-button keypad for operation.
Inputs and Outputs: The system supports multiple inputs including 4–20 mA for external level sensors and digital inputs. Outputs include 0/4–20 mA with a load of 500 Ohm and 5 relays loadable up to 230 V AC.
Measurement Principles: The OCM F uses Doppler technology for flow velocity measurement and piezo-resistive pressure measurement for level detection. The measurement frequency is 1 MHz for wedge sensors and 750 kHz for pipe sensors.
Applications: The flow meter is applicable in wastewater treatment plants, storm water management, industrial wastewater networks, and more. It is designed for easy installation and operation, with multilingual programming and simulation options for diagnostics.
Key Features: The OCM F features intelligent Doppler technology, easy mounting, multilingual programming, and robust construction for use in polluted and abrasive media. It includes an integrated 3-step controller and mechanically protected pressure measurement cell.
