WEDGE METER

1. THE CHARACTERISTIC

DHWM-F / DHWM-BW / DHWM-T Series Wedge Meter

is an flow gauge(meter) that measure quantity of flow

in poor conditions.

DHWM-F Series can be measure to quantity of flow

like as Liquid, Gas, Steam, aas well as fluid included

sludge.

Specially, it is suitable to measure quantity of flow for

flow fluid with high viscosity.

It is possible to measure both flow.

2. THEORY

DHWM-F Series estabilisbed Wedge of “V” type in

tube.

The quantity of flow is measured by pressure

difference of both side by means of wedge.

3. CAPACITY

Viscosity ±0.5% of measured value after

calibration(±3% before calibration)

Repeatability ±0.2

Maximum temperature 538�C

Range 10:1

H/D Ratio 0.2~0.5

Tube type 25A~600A
