Electromagnetic induction flow meters An electromagnetic flow meter consists of a sensor and a transmitter. The flow meter is used to measure the volumetric flow rate of conductive fluids and waste water. The measurement is independent of the density, viscosity, temperature and pressure. The conductivity of the fluid must be greater than 5μS/cm. The measuring instrument must not be crossed by fluids carrying solid bodies of high dimension that cannot be considered suspended solids. Head losses are absent and straight stretches reduced upstream and downstream of the instrument are necessary....

Ultrasonic “transit time” meters The 100F flow measurement system is composed of a digital converter for wall installation and two ultrasonic clamp-on or insertion transducers. The transit time of a fluid inside a pipe with a cylindrical section is the operating principle on which the instrument is based to calculate the value of the instantaneous flow rate. DSP, Digital Signal Processing, technology ensures low sensitivity of the system to any potential disturbing factors. The dimensions of the pipe may vary from 20 to 4000 mm (by using different transducers) while liquids can be:...

Portable “transit time” flow meters The 100H flow measurement system is composed of a portable digital converter and two ultrasonic clamp-on transducers. The transit time of a fluid inside a pipe with a cylindrical section is the operating principle on which the instrument is based to calculate the value of the instantaneous flow rate. DSP, Digital Signal Processing, technology ensures low sensitivity of the system to any potential disturbing factors. The dimensions of the pipe may vary from 20 to 4000 mm (by using different transducers) while liquids can be: ultra-pure, drinking water,...

“Doppler” effect flow meter The DFM-5.0 effect flow transmitter is suitable for most liquids, such as water, waste water, chemical liquids, sludge and viscous liquids. It controls, indicates, totalises and transmits the flow rate in gallons, litres or other units of measurement. The sensor is mounted on the outside of a pipe made of metal or plastic. To measure the flow rate, the acoustic pulses, generated by the sensor, are reflected by the particles or gas bubbles, present in the liquid, and are sent back to the sensor. Installation can be done without stopping the plant. There is no...

PDFM-5.0 The PDFM-5.0 Doppler effect flow meter is suitable for monitoring a flow rate or for identifying problems encountered in a closed pipe. It is an ideal instrument for evaluating the performance of flow meters inserted in line. It can be installed, calibrated and operated in a few minutes and then used as a temporary replacement for an in-line transmitter. Easy to transport Each PDFM-5.0 unit comes with a convenient and stylish carrying case, the sensor, and a stainless steel installation kit. The unit can be used for a short time or left in a position to transmit and/or record data....
