Magnetic flow monitor signal converter

Magnetic flow monitor signal converter

Ref: 10.8.1


Price: £936.00 / €1,141.92 (Excluding VAT at 15%)

Signal converter that sits on top or remote from the flange magnetic flow monitor. The unit is 230v AC 50 hz other options available). The head can be mounted remote from the flanged pipe fitting, or it can sit on top of the pipe. If remote displays or logging are required, the standard unit has a two wire 4 to 20 mamp analogue output. In addition there are relay out-puts that are user set to any given water flow. The enclosure is rated at IP67 for out-door use,  but it can be upgraded if required to underwater IP68 status.

The equipment is NEMAS certified, accuracy +/- 0.5% (reference conditions) repeatability, better than 1% at full scale.

Flanged PN40 flow electrode 45cubm/hr DN 40mm

Ref: 10.8.3


Price: £684.00 / €834.48 (Excluding VAT at 15%)

Flanged electrode section of the flow monitor. The liner is EPDM and the electrode is manufactured in hastalloy stainless steel. The unit is suitable for most water types including seawater, swimming pools, waste water, fish farms & chemical industry. There is no restriction to the flow of water with these units, the only conditions are that the temperature should be between 0 and 50 deg c, the water must be conductive ( eg not deionised or distilled water), and the the pipe must be full of water. The electrical supply for the electrode comes for the signal converter.

The flange sizes, and maximum water flowrates for each unit are given below, it is best to size a unit at approximately 1/2 to 2/3 rds of the maximum. The same signal converter is used with each unit.
