Flow Indicator - Measuring Device for Flow and Pressure

Description

Application

The flow indicator is a new simple measuring device for measuring flow and pressure in heating, cooling and domestic hot water systems.

The flow indicator consists of a differential pressure gauge and a slide ruler, which enables the pressure to be calculated into flow.

Find the presetting

Given: LENOTM MSV-BD 15, desired flow 500l/h Desired: Presetting

The slide ruler has been developed for Danfoss balancing valves.

The slide rulers can also help determine the presetting of balancing valves.

▪

Move 1st ruler to the desired flow e.g. 500 l/h or 10 kW.

▪

Move 2 ferential pressure (∆p), e.g. 0.1 bar.

Presetting can be read where the scale of LENOTM MSV-BD 15 is crossing the red line, in this example presetting = 4.

Determine the flow

Find out the dimension of the installed LENOTM MSV-BD valve and read the actual presetting (here DN 15 and presetting 4).

▪

Move 1

ruler to read presetting =

4 Read differential pressure on man-

ometer, e.g. 0.07 bar.

Move 2

ruler to 0.07 bar, and

read flow = 400 l/h To balance 500 l/h, change the

presetting or regulate the differential pressure.

Move 1st ruler to 500 l/h, and read new presetting = 4.5

Or adjust the differential pressure at the pump.

Ordering

The flow indicator can be used for manual balancing valves and partner valves for ASV:

▪

Leno ASV-I

▪

ASV-BD

▪

USV-I

▪

MSV-F2
