Tokyo Keiso VDT Series Water-Cone Flowmeter
Made in Japan
Manufacturer: Tokyo Keiso
Model: VDT series
VDT series is the indicator integrated type Wafer-Cone® differential pressure flowmeter; VH series Wafer-Cone® flowmeter and DT series multi digital differential indicator are integrated into one flowmeter.
Its principle is based on the Bernoulli’s theorem like orifice flowmeter. The V-cone inside pipe throttles flow and generates differential pressure corresponding flow rate.
The precision cast body made in lost wax process has a simple and rigid construction. Shorter straight runs and lower pressure loss than orifice save your construction cost and energy.
Features
- Easy installation with self- centering mechanism
- Direct mounting of compact differential pressure indicator requires no impulse piping
- Less than 1/5 of orifice straight runs
- Stable low differential pressure measurement allows wide rangeability
- Stable low differential pressure measurement allows low pressure loss
- Durable structure against wear or adhesion and maintenance free with stable operation
- Easy-to-change flow direction at field
- Easy-to-read big display and versatile indication functions
Applications
- Flue gas flow management
- HVAC(Heating ,ventilation and Air conditioning) system
- Water treatment facilities
- Refuse incinerator plants
- Co-generation plants
