Meter goes with the flow
E-T-A Circuit Breakers has a new 'plug and play' electronically controlled flow meter, offering rail, panel or surface mounting
E-T-A Circuit Breakers has a new 'plug and play' electronically controlled flow meter for water, offering rail, panel or surface mounting. Used in combination with E-T-A monitoring heads and adapters, the meter offers direct readouts of flow speed and flow volume measurement, while also providing analogue and signalling outputs.

E-T-A Circuit Breakers has introduced a cost-optimised version of its cubic-version smart power relay, called the E-T-A E-1048-8D, or Dice variant
The E-T-A FM 1-LQ flow meter measures water flow rates between 0.05 and 3m/s when used in conjunction with E-T-A CSP or CSF calorimetric monitoring heads.
The internal microcontroller offers menu-driven metering by the operation of keypads on the front of the unit.
Readout is given on a 2-line x 16-digit LCD.

The meter will display digital readouts of flow speed, flow volume (calculated from reference curves for the given pipe diameter), mass flow and water temperature, as well as minimum/maximum flow rates and temperatures during a given interval.
The readouts can be switched to bargraphs providing actual flow rate/quantity, medium temperature or preset limit contact status.
Other keypad combinations provide parameter setup and fault diagnosis.
The FM 1-LQ offers two scalable analogue outputs for flow and temperature, with a choice of current or voltage output.
Relay or transistor signal outputs are also provided.
These are manually preset via the keypad to switch at upper and lower limits: status indication, and a pulsed output of flow volume, can also be provided separately in the case of the transistorised output.
The E-T-A CSP-11 calorimetric monitoring head will measure from 0.02 to 21.2m3/h depending on pipe diameter.
It can be positioned accurately within pipes, and exchanged if required, by plugging into a TP sensor adapter.
The additional E-T-A BV ball valve enables simple, pressure-free, installation or removal of a CSP-11 monitoring head by closing the input and output pipe.
The screw-mounted E-T-A CSF-11 calorimetric monitoring head enables measurement of flow rates between 21 and 530m3/h.
It allows a variable immersion depth into pipes varying in diameter between 50 and 250mm.
The sensor probes are stainless steel as standard, or with Hastelloy or titanium to special order. Request a free brochure from E-T-A Circuit Breakers....
