It has a protection class of IP66/NEMA 4X. This high - level protection against dust and water ingress makes it suitable for use in harsh environments. Whether it's in a dusty industrial plant or an area exposed to water splashing, the Prosonic FMU90 can continue to operate reliably, ensuring the integrity of the measurement data and the longevity of the device.
In conclusion, the e+h Ultrasonic measurement Time - of - Flight Prosonic FMU90 is a highly versatile and reliable industrial measurement device. Its advanced features, wide range of applications, and excellent technical specifications make it an ideal choice for industries that require accurate and efficient level and flow measurement solutions.

Field of application:

Key Features:

Prosonic FMU90 separated version with field housing or top hat rail housing for control cabinet instrumentation are suited for continuous, non-contact level measurement of fluids, pastes, sludge and powdery to coarse bulk solids. Also the flow measurement in open channels and weirs is possible as the simultaneous measurement of level and flow in a storm water overflow basin with only 1 sensor. Up to 6 relays for tendency alarm, flow pulse output or backwater/sludge alarm, 1 or 2 channel version.

Level measurement of fluids and bulk materials with 1 or 2 sensors for measuring of up to 45m (148ft) and level limit detection. Pump control, rake control and as option: additional pump control function.

1.Calculations: Average, difference, sum
2.Application flow: Flow measurement in open channels and weirs with 1 or 2 sensors
3.Flow measurement with back water or sludge detection
4.Up to 3 totalizers and 3 counters
Counting or time pulse output for control of external units

1.Simple, menu-guided operation with 6-line plain text display, 15 languages selectable
2.Envelope curves on the display for quick and simple diagnosis
3.Easy operation, diagnosis and measuring point documentation with the supplied "FieldCare" operating program
4.Time-of-Flight correction via integrated or external temperature sensors
5.Linearisation (up to 32 points, freely configurable) for the most common flumes and weirspre-programmed and selectable
6.Online calculation of the flume-/weir-flows via integrated flow curves
7.Automatic detection of the sensors FDU9x

Versatile Mounting Options: 

Multiple Channel Capability:

Relay Functions: 

The Prosonic FMU90 offers great flexibility in mounting. It can be installed in the field using its field housing, which is designed to withstand harsh environmental conditions. This makes it suitable for outdoor applications or installations in industrial plants where exposure to dust, moisture, and temperature variations is common. Additionally, it can be mounted on a top - hat rail within a control cabinet for instrumentation purposes. This is convenient for applications where a more organized and protected installation is required, such as in control rooms or areas with multiple measurement devices.

Available in 1 or 2 - channel versions, the FMU90 can be configured to meet different measurement requirements. The 2 - channel version allows for more complex measurements, such as simultaneously measuring the level of two different substances in a multi - layer tank or using one channel for primary measurement and the other for backup or reference purposes. This versatility makes it adaptable to a wide range of industrial processes.

Equipped with up to 6 relays, the Prosonic FMU90 provides various control and alarm functions. These relays can be used for tendency alarm, notifying operators when the measured parameter is approaching a critical value. They can also be used for flow pulse output, which is useful in applications where the flow rate needs to be monitored and controlled. In addition, the relays can be configured for backwater/sludge alarm, ensuring early detection of potential issues in systems involving water or sludge management.
