CLA-VAL Automatic Control Valve to provide accurate flow measurement data without the need to install a separate meter. Configured to be installed in the inlet tapping of a CLA-VAL Automatic Control Valve, the e-FlowMeter can be used in valves directly downstream of a turbulent flow such as elbows, valves or reducers. The e-FlowMeter employs an innovative and patented swivel mechanism allowing the meter to be inserted into tappings as small as 1/2". - Page 5 4-20 mA, pulse or digital pulse to suit the desired application.

Page 15: Maintenance And Repair
DEALING WITH SENSOR TIP DAMAGE If the sensor tip is bent, broken or damaged in the course of the handling or installation, the e-FlowMeter will not function properly. The sensor should be straight with respect to the sleeve. Since it is designed to sense micro-motion, if the sensor is forced to enough to detect the movement with the naked eye, it may have been damage. -

Page 19: 4-20 Ma, Pulse And Pulse Digital Ouput Configuration
4-20 MA, PULSE AND PULSE DIGITAL OUPUT CONFIGURATION The e-FlowMeter is factory calibrated. Calibration depends on the model and size of the valve (see chapter 4.3 « Flow Parameters Factory Calibrated » for the corresponding values). But if necessary, it is possible to change the 4-20 mA scaling or pulse weight and pulse width. -
Page 20: Calibration
CALIBRATION According to table from chapter 4.4 « Dimensions », an e-FlowMeter size covers more than 1 valve model. For example, it is possible to take an e-FlowMeter calibrated for a NGE 80 valve and to recalibrate for a NGE 100 valve. To do this: Start the e-FlowMeter Software and click on "Calibration".
