Endress+Hauser instruments and spare parts

We source Endress+Hauser Promag, Promass and Prowirl flowmeters, Micropilot, Levelflex and Prosonic level meters, Cerabar and Deltabar transmitters, iTEMP and Memosens by order code.

Proline Promag electromagnetic flowmeters

Promag measures the flow of electrically conductive liquids such as water, wastewater, solutions and food media. The version defines the application: Promag W for water and wastewater, Promag H for hygienic processes and Promag P for high-temperature process applications.

To select a meter or an assembly, provide the full order code from the nameplate, for example 5H3B40-….

Promag W 300: 0.5 to 263,000 m³/h for water and wastewater.
Promag H 100: 0.06 dm³/min to 600 m³/h, hygienic design.
Promag P 300: PFA or PTFE liner, up to PN 40.
Measurement error ±0.5 % o.r., optionally ±0.2 %.

Promass Coriolis and Prowirl vortex meters

Promass measures mass flow, density, temperature and viscosity simultaneously, so it is used for raw material accounting, dosing and quality control. Prowirl handles liquids, gases and steam, including boiler houses. Selection is based on the order code, medium and flow range.

Promass F 300: up to 2,200,000 kg/h, liquid mass flow ±0.10 %.
Promass P 100 is designed for life sciences.
Prowirl F 200 detects wet steam, standard range −40 to +260 °C.
Prowirl D 200 is a cost-effective wafer version.

Micropilot and Levelflex radar level meters

Micropilot measures the level of liquids and solids without contact using free-space radar. Levelflex is a guided wave radar: the signal travels along a rod, rope or coaxial probe, which helps in narrow vessels and for interface measurement.

A replacement needs the order code, process connection and probe length.

Micropilot FMR10B, FMR20B and FMR30B for basic applications.
Micropilot FMR52: −196 to +200 °C, up to 40 m.
Levelflex FMP51: −50 to +200 °C, up to 40 bar.
Levelflex FMP52 with coated probe for aggressive liquids.

Prosonic ultrasonic level meters

Prosonic measures the level of liquids and bulk solids by ultrasound without contact with the medium. FMU40 works as a standalone device, while FDU series sensors connect to a separate FMU9x transmitter. State the full code and measuring range for selection.

Prosonic FMU40: liquids up to 5 m, solids up to 2 m.
FMU40 accuracy: ±2 mm or ±0.2 % of set range.
FDU91 sensor: liquids up to 10 m, solids up to 5 m.
FDU90 and FDU91 connect to an FMU9x transmitter.

Liquiphant point level switches and Liquicap

Liquiphant vibronic switches detect a liquid limit level for overfill protection, pump dry-run protection and minimum detection. Liquicap capacitance probes measure level and interface in small tanks and in build-up forming media. Provide the code, length and process connection.

Liquiphant FTL51B: −50 to +150 °C, up to 100 bar, for all liquids.
Liquiphant FTL31 and FTL33 are compact, FTL33 for food plants.
Liquiphant FTL64 for hot liquids up to +280 °C.
Liquicap FMI51: probe 0.1 to 4 m, up to 100 bar.

Cerabar, Deltabar and Deltapilot pressure transmitters

Cerabar measures absolute and gauge pressure, Deltabar measures differential pressure used for flow and level measurement, and Deltapilot measures hydrostatic level. The membrane type, ceramic or metal, the range and the process connection are all encoded in the order code.

Cerabar PMP71B: 400 mbar to 700 bar, accuracy up to 0.05 %.
Cerabar PMC21 with ceramic sensor, accuracy 0.3 %.
Deltabar PMD55B: 10 mbar to 40 bar differential pressure.
Deltapilot FMB50 with Contite cell: 100 mbar to 10 bar.

iTHERM thermometers and iTEMP transmitters

The Endress+Hauser temperature range includes industrial and hygienic thermometers, thermowells and iTEMP transmitters. A transmitter is mounted in the sensor head, on a DIN rail or in a field housing. Selection needs the sensor type, immersion length, process connection and output signal.

iTEMP TMT82: HART, two universal inputs, SIL 2.
iTEMP TMT162 field transmitter for hazardous areas.
iTEMP TMT31 with 4–20 mA, TMT36 with IO-Link.
iTHERM ModuLine modular industrial thermometers.

Liquid analysis: Memosens and Liquiline

Memosens sensors store calibration data in the sensor head and transmit the signal digitally to the transmitter via a bayonet connector. A sensor can be calibrated in the laboratory and quickly swapped at the measuring point.

Liquiline transmitters accept pH, ORP, conductivity and other sensor signals.

Memosens CPS11E pH electrode: up to 135 °C in application B.
Liquiline CM442: one or two Memosens digital inputs.
Liquiline CM42B two-wire single-channel transmitter.
Consumables: electrodes, buffer solutions, Memosens cables.

Order code and serial number

An Endress+Hauser nameplate shows the order code and the serial number. The first characters of the code are the product root, for example 5H3B for Promag H or FMR20B for Micropilot; the rest encodes nominal diameter, materials, outputs and approvals. Photograph the whole label without glare.

The manufacturer finds spare parts by product root, order code or serial number, and the serial number also leads to documentation, successor products and spare parts data. Send the serial number together with the code, even if the device still works.

Electronics module, display or complete device

When a device fails, compare the options: a separate electronics module, display, sensor or a complete device. For a module, state its designation and the code of the device it belongs to. For a flowmeter, note whether the sensor or only the transmitter is needed.

The repair decision belongs to your instrumentation team or service provider. We quote both the assembly and the complete device so that scope and lead time can be compared.

Flowmeters: what to send

For Promag, Promass or Prowirl, provide the full order code, nominal diameter, process connection, medium, process temperature and pressure, and required outputs: 4–20 mA, HART, pulse or fieldbus. For hygienic versions, state the connection type and seal material.

If only the electronics are replaced, photograph its label separately from the sensor label. For Coriolis meters add the flow range and medium density; for vortex meters add the steam or gas conditions.

Level and pressure instruments: what to send

For Micropilot, Levelflex, Prosonic, Liquiphant, Cerabar or Deltabar, provide the order code, process connection, measuring range, medium, temperature, pressure and output signal.

Probe length matters for guided radar and capacitance probes; fork length and mounting position matter for point level switches.

State explosion protection and wetted material requirements. For food plants, attach a photo of the process connection, since hygienic fittings differ by standard.

Liquid analysis consumables

pH electrodes and conductivity sensors wear and are replaced more often than other parts. An order needs the full sensor designation, for example CPS11E-AA7BTA2, plus the assembly and transmitter type. Memosens cables are selected by length and connector, buffer solutions by pH value and volume.

Memosens sensors connect to transmitters with a Memosens digital input. If the site still uses older analog sensors, say so: transmitter input compatibility must be checked before replacement.

Updated codes instead of older ones

Many requests arrive with older codes such as FMR20, CPS11D, PMP55, FMR230 or Promag 10. Our quotations have included updated items: FMR20B instead of FMR20, CPS11E instead of CPS11D, PMP43 instead of PMP55 and FMR54 instead of FMR230.

Each substitution is checked against the order code, process connection, range and output signal. The final decision rests with your specialist, because dimensions and settings of the newer version may differ.

If the code is not in the current catalogue

If a device is discontinued or its code is not in the current catalogue, start with the serial number: the manufacturer uses it to show successor products and spare parts data. We check whether the same device or assembly can be supplied and prepare an option with a current version in parallel.

Before replacement, save the device settings: range and output scaling for a flowmeter, tank parameters and calibration for a level meter. This shortens reconfiguration after installation.

Equipment for a new project

For a new project, start with the task: measured variable, medium, range, temperature and pressure, accuracy and explosion protection requirements, and the interface to the control system. If a designer data sheet exists, attach it: selection against a data sheet is faster and more accurate.

We propose versions from the current manufacturer portfolio and mark the parameters that your designer should confirm before ordering.

Agreeing the delivery list

Before ordering, check the codes in the list against the instrument markings and attach a nameplate photo for each item. List flowmeters, level meters, pressure and temperature instruments, analysis equipment and spare assemblies separately to simplify checking the shipment.

Name an instrumentation specialist who will confirm range, connection, materials, output signal and explosion protection. On receipt, compare the order code on each nameplate with the agreed list before installation.

Limitations: this page does not confirm official Endress+Hauser partner or dealer status, manufacturer warranty or service, availability, price or lead time, interchangeability based on a series name, or substitution with other brands.

These terms are verified for each request and stated in the quotation.
