Flow Meters

Flow meters are devices that measure the amount of liquid, vapor or gas that passes through them. Flow meters consist of a primary device, a transducer and a transmitter. After the transducer senses the liquid or gas that has passed through the primary device, the transmitter will create a usable electrical signal that can be transmitted and received by other control devices or instruments. There are several things to consider when selecting a flow meter. The type of media to be measured: liquid, vapor or gas. The flow measurement type: velocity, volumetric or mass. The pressure and temperature of the media. The required flow range and accuracy.

Tek-Trol Tek-Clamp 1200A Ultrasonic Clamp On Flow Meters are designed to measure the fluid velocity of liquid in a full or closed pipe. They operate according to the difference in Transit Time of Flight measured and determines the flow velocity by measuring the travel time of a pulse from one transducer to the next.

Tek-Trol Tek-Vor 1300C Vortex Flow Meters calculate the mass flow, volumetric flow rate, pressure, temperature and density of any liquid, gas or steam through a pipeline.

Tek-Trol Tek-Flux 1400A Electromagnetic Flow Meters, also called Magmeters, measure volumetric flow rates of any fluid which can adequately conduct electricity in closed pipelines. They are highly reliable, accurate and stable devices that are used in various high-pressure industrial processes.

Dwyer Series RM Rate-Master Flow Meters are suitable for both liquid and gas applications. The series consists of 2 inch, 5 inch and 10 inch scales that can be surface or panel mounted with optional precision metering valves.
