Piston type
Suitable for liquids and high pressures, a spring loaded piston/
magnet sensor is magnetically coupled to a pointer to indicate a
pressure difference.
Sensing element is completely separated from the indicator, switches, relay or transmitter. A high pressure rated housing is machined from single block making them a natural for high pressure applications. Select from the widest variety of materials and configurations in the industry. Available also with glycerine
filling to avoid vibrations.

Diaphragm type
With diaphragm sensing element are suitable for air or gaseous fluids. Built on a design similar to the piston units, but with a diaphragm that replaces the piston and separate the high-low pressure ports, without any by-pass. A variety of different diaphragm designs are available for all applications and ranges, further to a wide choice of materials, also according NACE.

2020_ Low cost fl owmeter with high sensitivity
2220_ Easy to read linear scale, high pressures up to 350 bar
2320_ 1/2“ ports allow higher fl ow rates, up to 40 LPM
2420_ From 0-40 LPM up to 0-110 LPM with static up to 100 barg
(1” pressure ports)

A wide range of flow rates can be measured with our variable area flowmeters.
The sensor, a magnet/Delrin® cone, rests in a precision orifice and is deflected by fluid flow. As flow increase, the pointer that is magnetically coupled to the sensor, indicate the flow rate on an easy to read dial. For measures from 4 LPM up to 110 LPM for liquids and from 3 Nm3/hr up to 150 Nm3/hr for gases.
Are available different versions: only local indicator, or with switches, or with 4-20mA transmitter.
