Remote measuring points
Consider battery-powered measurement for remote water and irrigation pipelines. Battery life, measurement settings and communication requirements must be evaluated together.
TEM82E and W803E+ are source converter references. The final ATLAS order code is determined by the sensor and converter configuration.

Questions before selection
Which flow meter should I choose?
Evaluate the measurement objective, fluid, flow range, pipe and installation conditions together. Electromagnetic, clamp-on and in-line ultrasonic technologies serve different requirements.
Can an electromagnetic meter measure any liquid?
No. The liquid must have sufficient electrical conductivity and be compatible with the lining and electrodes. This method is not suitable for gas, steam or insufficiently conductive liquids.
Can I measure without mains power?
A suitable battery-powered converter can be considered. Communication and analogue outputs may require additional modules and external power.
Can I measure without cutting the pipe?
Consider the clamp-on ultrasonic family. Pipe material, outside diameter, wall thickness and acoustic conditions must be suitable.
Is AtlasServer.io or SCADA connectivity standard?
Connectivity depends on the selected equipment and project scope. Protocol/register maps, modules, power supply and gateways must be validated together.
What information is needed for a quotation?
Provide the fluid, minimum/normal/maximum flow, DN, pressure, temperature, connection standard, power and communication requirements. For clamp-on meters, include pipe outside diameter, wall thickness and material.
