Spirax Sarco Level Control

Spirax Sarco Controls & Flowmeters

Boiler Controls

Accurate control of water level/alarm within the boiler or tank while maintaining the proper TDS level of the boiler water is vital in the boiler room.


No matter what your thermal energy management goals are, Spirax Sarco’s range of flowmeters can help assess your thermal energy production, usage, and distribution. Our flowmeters have an unrivaled reputation for accuracy, turndown and reliability. Advanced communication and configuration capabilities make our flowmeters suitable for your current and future needs. A comprehensive selection of flow computers which can be linked to plant and building management systems, complement the range.

Available Products

Modulating Level Control

A level control system consists of a sensor, controller, valve or pump and may be on-off or modulating. It is vital that your boiler water levels be monitored safely and accurately.

Boiler Blowdown & Condensate Contamination Detection

The BCS 3 blowdown system is suitable for shell and water tube boilers and can be linked to energy/building management systems. The BCS 3 can handle boiler pressures up to 465 psig.

Gilflo Flowmeters

Variable area pipeline flowmeter with high turndown capability. Comes as spring loaded variable version and in-line variable area version.

TVA Meters Target Variable Area flowmeter (TVA)
Insertion Turbine RIM

Spirax Sarco’s insertion turbine flow meters provide significant cost savings for line sizes from 3 to 80′ without compromising performance.


Spirax Sarco Vortex meters have no moving parts, rugged construction, and microprocessor-based electronics for high accuracy in many flow metering applications including liquids, gas and steam.

Thermal Mass Flowmeters MTI10/MTL10

Measures the mass flow of gases and air without the need for additional transmitters or flow computers, and is virtually immune to changes in temperature and pressure over a wide flow range.

Ultrasonic UTM10 Non-Intrusive Ultrasonic Liquid Flowmeter

Ultrasonic meters clamp-on to the outside of the pipe and measure fluid through the use of ultrasound signals. They do not come into contact with the fluid and therefore do not create pressure drop, or contaminate fluid.
