ELECTROMAGNETIC FLOW METERS

Introduction

These flow meters are capable of supervising the flow of fluids in pipes. They measure the flow by means of an acoustic signal which is reflected by a sensor in gas bubbles or particles in the fluid.  It is also recommended for full piping with fluids that may contain foods or bubbles.

HOW IT WORKS

The sensor is easy to install in a few minutes. It is mounted on a belt on the plastic or metallic tubing.  This belt has a fastener that assures a correct alignment   and can be mounted on horizontal or vertical piping.

The installation is quick and simple and does not require stopping the flow nor cuts or other interventions with the tubing.  The system is never in contact with the fluid.

This system is implemented in flows such as:
Viscous liquids
Acids
Mixtures
Solvents
Treated industrial waste waters
Sludge, slurries
Pulp slurry
Lubricating oils
Fluid foodstuffs
Crude oil
Chemicals

Recommended material for the piping: PVC, carbon steel, stainless steel, cast iron, fiberglass reinforced plastic, and any material that will transmit ultrasonic emission

DOPPLER METERS

Introduction

A magnetic sensor is utilized to measure variation of level (or flow in Parshall Flume)
for control of industrial wastewater and also viscous  or corrosive liquids.

Control switches can be programmed and used for level alarms or controlling pumps.

The sensor is sealed to prevent damage during accidental submersion.

How it works

This sensor is mounted on the top of a tank or Parshall Flume to supervise the level in a continuous mode. It is quick and easy to operate thanks to its simple method of calibration.  It can also work with different measuring units, gallons, litres, centimetres, percentages. It may be installed in round horizontal or vertical tanks. It has the particular feature that it seeks the best signal and adjusts itself, avoiding and filtering false echoes, thus delivering a correct and exact level measure.

Technical specifications

Direct connection to a PLC or computers and is nominal for R=1000 Ohms. Compensations can be programmed between 4 and 20 mA for use in special controls.

A digital display shows the flow index while a 16 digit display shows the total flow.

The sensor is mounted on the upper part, so that dirt does not affect it and maintenance is not required.  It has a built-in temperature sensor for itself, so it maintains exactitude (+0.25% of the full scale) to adjust to ambient conditions.

The software of your PC can determine the formula for adapting to whatever is being measured.
