Clamp-on installation for pipe sizes of DN40 ... DN1200

The SUTO S461 Ultrasonic Clamp-On Flow Meter for Water and Other Liquids is an all-in-one solution to provide reliable, cost-efficient and accurate flow and consumption measurements of water and other liquids. Based on the transit time technology, S461 flow meter comes with unique features and outstanding performance.

Easy Clamp-on Installation

The S461 Smart Flow Meter is simply clamped onto the outside of the pipe and never comes in contact with the fluid. With its robust design, the main unit can be installed onto the pipe itself, on the wall or onto a DIN rail. The Flow Meter supports pipe sizes of DN40 … DN1200.
The liquid flow and consumption can be measured in both directions (Bi-directional measurement).

Can Be Used as Portable Version

The S461 is also available as a portable version in a carrying case. This allows the flowmeter to be used flexibly for different measuring locations.

Smart Configuration trough App

The configuration and setups are done through the wireless smartphone app S4C-US which can be downloaded for free from the SUTO website, Google Play Store and the Apple App Store. The app allows the user to set up the device as well as read live values, logger configuration and read out logger data. Has the ability to get an instant view of daily, weekly and monthly consumption.

Efficiency Monitoring of Heat Exchangers

By adding 2 clamp-on temperature sensors, the S461 can be used as an Energy Meter. This makes it easy to monitor the efficiency of heat exchangers as well as the liquid flow in just one device. Heat exchangers transfer heat (energy) from a higher temperature medium (hot stream) to a colder one (heated stream). S461 measures the flow rate and the temperature difference between cold stream and heated stream. Based on these measurements the recovered energy will be calculated.

Connection to Monitoring Systems

The S461 Flow Meter can be easily connected to any monitoring system through various signal interfaces: Modbus/RTU (standard), 4… 20 mA / Pulse / Alarm-Relay (optional), Modbus/TCP (optional).

Various Applications

The S461 Ultrasonic Flow Meter is used in various applications, such as Cooling / Heating / Process Water; Purified Water Measurement; Fuel, Oils, Petroleum Products; Water Treatment; Food / Beverage and more.
