MEGAUF89 Series ultrasonic flow meter system for open channels employs the latest in ultrasonic technology. Utilizing our wealth of know-how and technical expertise, the MEGAUF89 Series ultrasonic open channel flow meter provide accurate and stable flow measurements. It is applicable for liquids with free surfaces such as agricultural water, river water, waste water and industrial effluents.
- MEGAUF89 Series Open Channel Flowmeter can show level, space, distance, time or flow on the display.
- The relays can be programmed to activate alarms, pump starters, or other control devices. There is an isolated 4-20 mA output that can be connected to a chart recorder or PLC, to monitor level space or distance, independently from that shown on the display.
- There is an RS485 port, so that the MEGAUF89 Series Open Channel Flowmeter can be operated remotely by a PC or other devices.
- All the parameters are stored in non-volatile memory, so the information is retained in the event of power interruption.
