E+H Ultrasonic Level Transmitter, FMU90-R11CA111AA3A

Product Introduction Overview

Ultrasonic Measurement

Travel Time Principle

Prosonic FMU90

The transmitter can be field-mounted or rail-mounted, and can connect up to 2 sensors - FDU90/91/92/93/95

The Prosonic FMU90 can be field-mounted or rail-mounted in an instrument control cabinet. It is suitable for continuous, non-contact level measurement of liquids, slurries, sludge, powders, and solid lumps. It can also be used for flow measurement in open channels and weirs.

A single sensor can simultaneously measure the level and flow rate of rainwater overflow tanks.

It can have up to 6 relay-triggered trend alarms, flow pulse output alarms, or return water/sludge alarms, and is available in single-channel or dual-channel models.

Product Features

• Simple menu-guided field operation with six lines of plain text display, 15 languages ​​selectable

• Field envelope display for simple instrument fault diagnosis

• FieldCare operating software is provided, allowing users to easily perform remote operation, fault diagnosis, and measurement point file creation for the instrument

• Stroke time calibration via built-in or external temperature sensors

• Linearization function (up to 32 points) converts measured values ​​into length, volume, or flow rate in any unit

• Online calculation of canal/measuring weir flow rate based on built-in flow curves

• Automatic recognition function for FDU9x sensors

Product Applications

Applications in Level Measurement

• Equipped with 1 or 2 ultrasonic probes, it can perform continuous, non-contact level measurement of liquids, pastes, slurries, dust, and rough-surfaced lumpy materials

• Measuring range ≤70m
  

(depending on the specific probe model and the type of material being measured)

• Limit detection (up to 6 relays)

• Multi-stage pump control
  

• Grid control
  

• Calculated values: average, difference, and sum

Applications in Flow Measurement

• Equipped with 1 or 2 ultrasonic probes for flow measurement of media in open channels and measuring weirs

• Simultaneous measurement of level and flow rate of media in overflow conditions using only 1 probe

• Flow measurement with backwater detection (2 probes) or sludge detection function

• Up to 3 accumulators (non-resettable) and 3 counters (resettable) can be configured

• Provides counting pulse output or time pulse output for controlling external units

Plain language sourcing guide for E+H Ultrasonic Level Transmitter, FMU90-R11CA111AA3A

Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.

Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.

Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.

If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.

Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.

Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.

Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.

Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.

For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.

For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.

For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
