ST502 0.5-Level Clamp-on Type Ultrasonic Flowmeter
Ultrasonic flow meters that use transit-time methods to measure flow.
Introduction
ST502 is a high-accuracy ultrasonic flow meter, which supports the large diameter of DN25~DN5000. Clamp-on type and insertion type sensors can be selected, and different sensors have their own relative advantages:
The clamp-on type does not contact with liquid, and can measure various liquids. It does not need to stop production during installation. It is supported in various pipelines such as carbon steel pipes, cast iron pipes and PVC pipes, and is suitable for measuring related scenes such as medical, beverage and drinking water.
Insertion type measurement is relatively stable, and can also be installed online with pressure, without stopping production. It supports various special pipelines such as cement pipes and cast iron pipes, and is suitable for measuring water consumption in sewage plants, irrigation, industrial production processes and other related scenarios.
Advantages of products:
Stable measurement: the flow accuracy of 0.5% can bring high-quality data after successful installation.
Various output: ST502 has its own analog output: 4-20mA, pulse output: 0 ~ 999Hz, OCT, relay output: SPST, max 1Hz, Modbus protocol interface RS485.
Clear interface: back lit LCD, 16 touch buttons operation. The system is in menu mode, and all data can be selected and modified in the menu, which gets rid of the traditional code setting and is more convenient and simple to use.
Solid hardware: ST502 mainframe shell adopts aluminum alloy CNC technology, which is not afraid of bumping, solid and reliable. The sensor adopts twisted-pair shielded cable, with a standard length of 10 meters and a maximum length of 305 meters.
Applications
Clamp-on flow measurement of drinking water, process water, sea water, demineralized water, wastewater, and tolerant of liquids with small amounts of air bubbles or suspended solids.
