High Temperature Flow Meters

High Temp Flow Rate MeterFor 1/8"- 2" Pipe SizesCE

Style H & J

Enables flow monitoring of barrel heating fluids, thermal transfer fluids such as Syltherm® coolant flows through heat exchangers, as well as flows through hydraulic circuits and sub-circuits with elevated temps.

CHOICE OF THREE MATERIALS OF CONSTRUCTION
Select from aluminum, brass or stainless steel to meet system requirements.

UNRESTRICTED MOUNTING
Allows the designer to install the meter in any orientation – horizontal, vertical or inverted.

GOOD VISCOSITY STABILITY
A sharp-edged stainless steel orifice provides excellent measurement stability for viscosities ranging from 0-500 SSU.

RUGGED AND RELIABLE
Designed as a hydraulic service tool, this meter will provide years of maintenance-free performance.

HIGH PRESSURE OPERATION
The magnetically-coupled follower design allows operation to 6000 PSIG and use with opaque liquids.

24 DIFFERENT PORTS AVAILABLE
Standard selection of NPT, SAE and BSP ports reduces the amount of adapters required for installation.

LOW COST ACCURACY
± 2.5% of range accuracy in center third of scale; ±4% in upper and lower thirds.

BI-DIRECTIONAL AND REVERSE FLOW OPTION OFFERED
High temperature meters are also available in bi-directional and reverse flow versions. Contact Lake Monitors for more information.
