PT. Java Atha Instrumentasi is one of the leading distributor and stockist field instrument in the world.

This meter’s design provides longer lasting accuracy and lower permanent pressure loss than orifice type meters, reducing maintenance and operating costs. The Venturi flow meter can be built to meet the highest pressure and temperature specifications often limited in other flow meter technologies.

 

Features :

Provides longevity, reliability and long term performance, Provides an un-calibrated accuracy of ±0.75% with a repeatability of ±0.1%, Reduced pumping costs, Durable solution for liquids, gas, steam and mixed media, Easily installed in any position with minimal straight pipe requirements.

Insertion electromagnetic flow meter designed to measure the fluid velocity of conductive liquids in applications where hot-tap or insertion installations are preferred.This insertion mag meter is available in four standard lengths and in permanent locations where cost or space limitations preclude the use of inline meters.

Flow meters using annubar sensors are rugged, tolerating high temperatures and pressure – up to 700C and 400bar. They can be used for steam, gases and liquids with six models covering pipe or duct sizes from 50mm to 15M. The Annubar Flowmeter is highly developed and can do the flow calculations and recommend systems, including DP transmitters.

 

Features of Annubar Flow Meters

• Suit, air, gas, flue gas, water, saturated and superheated steam etc
• Tolerate wide temperature and pressure ranges 700C and 400 bar
• Accuracy to 1% and repeatability to 0.1% with 10:1 range

Custody transfer is one of the most important applications for flow measurement. Many flow measurement technologies are used for custody transfer applications; these include differential pressure DP flow meters, turbine flow meters, positive displacement flow meters, Coriolis flow meters and ultrasonic flow meters.Custody transfer requires an entire metering system that is designed and engineered for the application, not just flowmeters.

 

Components of a custody transfer system typically include:

Flow computers
Quality systems (gas chromatographs for natural gases)
Calibration using in-place or mobile provers for liquid, or master-meter for liquid or gas

Differential pressure flowmeters, also known as DP flowmeters, create a cross sectional change in the flow tube, which causes the velocity of the flowing fluid to change. This flowmeter can be applied to relatively clean fluids. With proper attention to materials of construction, the flow of corrosive fluids, such as are found in the chemical industry, can be measured.
