Sensor for compact meter version
In compact meter version, the transmitter is attached to the meter sensor by means of a steel column with a stainless-steel flange. This flange is provided with two threaded holes to facilitate connections for potential equalising conductors.
Sensor for remote meter version
Sensor manufactured in the standard protection class IP 67 includes a terminal box. In the case of the sensor protection class IP 68, the signal cable conductors are permanently connected to the sensor terminals and the terminals inside the connection box are embedded in an insulation compound. The other end of the signal cable is provided with a connector facilitating connection to the meter transmitter.
The flowmeter component parts made of carbon steel are coated with polyurethane paint, the connection box with powder paint. The surface finish of all-stainless-steel sensor housing consists of shot blasting.
Attached to the sensor housings are sensor rating plate and an arrow indicating the positive fluid flow direction.
The connections to the sensor terminal box are described in Chapter 5 (ELECTRICAL CONNECTIONS).
