VARIABLE AREA FLOW METER - VA40
The VA40 is a glass tube variable area (VA) flowmeter for flow measurement of liquids and gases. The all-purpose flowmeter is suitable for all basic applications up to +100°C / +212°F and max. 10 bar / 145 psi. Typical applications include flow measurement of flushing, purging or inert gases or heating and cooling circuits.

VARIABLE AREA FLOWMETER FOR LIQUIDS AND GASES - H250 M40
VARIABLE AREA FLOWMETER FOR LIQUIDS AND GASES
- Modular design: from mechanical indicator to 4…20 mA/HART®7, FF, Profibus-PA and totalizer
- Any installation position: vertical, horizontal or in descending pipes
- Flange: DN15…150 / ½…6″; also NPT, G, hygienic connections, etc.
- -196…+400°C / -320…+752°F; max. 1000 barg / 14500 psig
The H250 M40 is the standard variable area (VA) flowmeter for the process and OEM industry. The VA meter combines mechanical flow measurement of liquids or gases with state-of-the-art communication capabilities. The device is modularly extendable. Additional electronic modules can be added or replaced at any time without process interruption. In this way, its functionality adapts to new requirements – from analogue flow measurement without auxiliary power to digital integration into a fieldbus system.

MASS FLOW METER
The function of mass flowmeters is based on the Coriolis principle. They allow for a direct measurement of mass flow, density and temperature of liquids and gases as well as calculation of volume flow and mass or volume concentration with a single device
Typical applications include:
- • Chemical: measurement of concentration or density, bulk loading, batching to reactors, hydrocarbon cracking, aggressive, abrasive or viscous media or media of unknown composition
- • Food & beverage: filling machine applications, measurement of degrees Brix, flow, density, specific gravity, and additive components dosing
- • Pharmaceutical: batching, dosing and filling, solvent extraction ultra-pure water measurement
- •Water & wastewater: flocculent dosing, sludge flow
and density measurement
- • Pulp & paper: paper stock, pulp, additives, bleaches,
colourants
- • Oil & gas: metering skids, bypass density measurement,
CNG/LPG dispensers, leak detection, custody transfer applications such as tanker loading, bunkering and pipeline transfer
