- VH series Wafer-Cone differential pressure flowmeter and high precision differential pressure transmitter are integrated into one flowmeter.It can measure liquids, gases and saturated steam including all high temperature fluids. It serves flow measurement for wide range of application such as air conditioning pipe lines, water treatment facilities and various chemical plants.
- Simple installation : Wafer connection makes installation simple. Flowmeter body flanges designed to match the pipe flanges guide to the pipe center line.
- Short straight runs : The required straight runs are less than 1/5 of those required for orifi ce and vortex flowmeters. The narrow installation space allows simple and flexible piping arrangement plan. It leads to space and cost saving.
- Low pressure loss : A proper selection of β ratio allows lower pressure loss than orifi ce plate with the same flow rate. It improves energy efficiency of the plant.
- Wide rangeability : Since the differential pressure created by the meter is stable at low flow rate, it can measure the flow rate in the range of the turn down ratio 14:1 to cover the wide flow range with one flowmeter. This flowmeter is best suited for the measurement of saturated steam line for air conditioning system whose flow rate is fluctuated at every change-over of cooling and heating.
- Wear and adhesion resistant : V shape cone has durable structure against wear or adhesion. It can measures challenging slurry or flue-gas process lines that ordinary orifi ce could not deal with.
- No connecting tube work required : The connecting tube work was required for the installation of the existing differential pressure flowmeter, but a compact differential transmitter has been directly mounted, resulting in saving the installation cost.
- 3-way stopcock installed : With only one-touch operation, a newly developed 3-way stopcock (Patent is pending) works better than three way manifold. This stopcock prevents mechanically such wrong operations as running off seal liquid in the impulse piping and over-pressurizing to the one side of differential transmitter which might occur with the traditional three way manifold.
- Indicator and highly functional transmitter combined : The LCD indicator with backlight LED allows easy reading as LED indicator at dark place, even at night. The instantaneous flow rate and integrating flow quantity alternately are indicated manually or automatically. The transmitter transmits the totalizing flow pulse signal (Open collector signal) in addition to the 4 to 20mA output with 2-wire system.
- Available in all directions : Vertical type has been added to the line-up, namely Bottom to Top,Top to Bottom, Left to Right, & Right to Left.
