Continuous Measurement vs Point Level Detection A level transmitter and a float level switch can both monitor liquid in a tank, but they provide different information. A transmitter measures level continuously and sends a variable signal to a display or control system. A switch changes state when the liquid reaches a defined point. Confusing these…
Which Meter Fits Gas, Steam or Liquid Flow? Thermal mass, turbine and vortex flow meters can all appear in gas and utility measurement projects, but they do not measure flow in the same way. A thermal mass meter responds to heat transfer, a turbine meter measures rotor speed and a vortex meter detects the frequency…
Start With Pipe Fullness, Conductivity and Installation Water and wastewater projects do not all use the same type of flow meter. A treated water pipeline, an old municipal main, a sewage pumping line and an open effluent drain have different hydraulic and installation conditions. Selecting among electromagnetic, ultrasonic and open channel technologies requires one basic…
What to Check Before Choosing a Flow Meter Manufacturer Choosing a flow meter is not simply a matter of matching the pipe size and placing an order. The correct instrument must suit the fluid, flow range, pressure, temperature, installation conditions and control system. A meter that performs well in clean water may fail in steam,…
EM Flow Meter Installation & Common Errors Accurate liquid flow measurement is critical for process control, chemical dosing, and utility management, but even the highest-quality instrument will fail if installed improperly. A proper electromagnetic flow meter installation ensures reliable data, while poor mechanical or electrical practices lead to immediate operational headaches. Incorrect installation can cause…
