SITRANS FMS500

3/37

Overview

The SITRANS FMS500 is a magnetic flowmeter sensor suitable for volume flow measurement of liquids (conductive) and is the ideal product for applications in water abstraction, wastewater treatment, water distribution networks, and irrigation.

The rugged, fully welded design supports direct burial, constant flooding and to stand up a wide range of harsh chemicals found in water-based applications in many different industries.

Designed for highly accurate measurement in low-flow conditions, these meters can measure from very low velocities up to 10 m/s, giv ing it a very wide measurement range.

Combined with a flowmeter transmitter it is a traditional externally powered electromagnetic flowmeter system

Benefits

• Zero Up and Zero Down installation capabilities

• NBR rubber liner for all water and wastewater applications

• EPDM liner specifically for drinking water applications requiring special approvals

• Soft elastomer facing provides high abrasion resistance

• Increased low flow accuracy for water leak detection

• Rugged construction with no moving parts for maintenance-free operation over many years

• Simple on-site upgrade to IP68 of a standard sensor allowing underground installation, permanent immersion or underwater installation

• Integrated grounding electrodes – no grounding rings required for many applications

• Short delivery time

• Built-in length according to ISO 20456 (up to DN 400 mm)

• SENSORPROM™ Technology provides an automatic upload of start-up settings and calibration data for easy commissioning

• Designed to allow in-situ verification for easy performance check

• In conformity with ISO 4064, OIML R49 and EN 14154

• Custody transfer approvals for cold water billing (MI-001)

Application

• Water abstraction

• Water treatment

• Water distribution network (leak detection management)

• Custody transfer water meters

• Irrigation

• Waste water treatment

• Filtration plant (e.g. reverse osmosis and ultra-filtration)

• Industrial water applications

The SITRANS FMS500 with its NBR or EPDM rubber lining is a flow meter sensor for all kinds of water applications such as ground water, potable water, cooling water, wastewater, sewage, or sludge applications.

Connected to the compatible transmitter SITRANS FMT020, either mounted remotely or as a compact unit, it forms the magnetic flow meter system SITRANS FM520 which can be used in almost all gen eral-purpose water applications.

SITRANS FM520

Perfect match for a cost-effective solution for all water and wastewa ter applications. Standard measuring accuracy ±0.4% of the actual flow rate, optional a high accuracy calibration with ±0.2% of flow actual rate is available.

MI-001). It also meets OIML R49 recommendations for Class 1 and 2 (Water meters for cold potable water and hot water).

Extensive testing has ensured its superior measurement accuracy, even under challenging inlet and outlet conditions. This allows for flexible installation in tight spaces without the need for pipe re-rout ing, as the FMS500 functions as a 0D/0D device for both Class 1 and Class 2 accuracy, requiring no inlet or outlet sections.

Furthermore, while primarily a cold water meter, the FM520 has been rigorously tested and passed at temperatures up to 50 °C (122 °F), including 30 °C (86 °F). This robust performance means it can be used for custody transfer (CT) purposes up to 50 °C (122 °F).

Sensitivity class U0D0 (The meter requires 0xD straight pipe upstream and 0xD straight pipe downstream from the sensor)

Temperature class • T30 (0.1 ... 30 °C)

• T50 (0.1 ... 50 °C)

Pressure MAWP 16 (Maximum Allowable Working Pressure) Electromagnetic class E2 Mechanical class M1, Class B and O (building and outdoors) Climatic class -20 ... 55 °C (-4 ... 131 °F) Power supply • 12 ... 42 V DC, 12 W

• 100 ... 240 V AC, 50 ... 60 Hz, 25 VA

Software Designed according to WELMEC 7.2

Communication modules 1)

HART, PROFINET, MODBUS and ETHERNET IP have been certified and can only be used where national regulations permit it. The reading of ancillary devices may be used for testing and verification and for remote reading of the water meter.

1) Communication module need to be ordered together with the system (FM520), a retrofit of the communication module is not possible since it would break the CT seals.

Special MI-001 settings:

• Unit: m³

• Low flow cut-off: 0.9 mm/s

• Digital output: pulses

For other factory settings, see the operating instructions.
