Product catalog summary

Introduction
Mass Flow ONLINE B.V. offers flow measuring and controlling products available for order 24/7 through their website. Most products are in stock and shipped worldwide within two working days.

Description
The LIQUI-VIEW Base series provides a compact, lightweight, and cost-effective solution for monitoring the flow of water-like liquids. Its unique design makes it one of the most compact vortex meters available.

LIQUI-VIEW Base Series
These meters operate on the vortex principle, using a bluff body to create vortices detected by a piezo-electric sensor. They can be mounted in any position and are available in ranges from 0.5 l/min to 150 l/min with a maximum pressure rating of 12 bar. Options include a display for local readout and analog or pulse output.

Features

No moving parts, making it maintenance-free and impervious to hard water deposits.
Low pressure drop and fast response.
Suitable for dirty water and sustainable design with low power consumption.
Available with a tilting display for local readout.

Fields of Application

Drinking water
Cooling water monitoring
Deionized and ultra-pure water distribution

Technical Specifications
Acceptable liquids include various types of water. The maximum operating pressure is 12 bar at +40°C, with different limits for higher temperatures. The accuracy is less than 2% RD at ≥ 50% FS and less than 1% FS at < 50% FS. The rangeability is up to 1:20.

Model Specifications
Models range from LVB-06 to LVB-25, with varying capacities and outputs. Each model has specific dimensions, weights, and admissible locking torques.

Approvals and Materials
The meters have drinking water approvals and comply with EMC standards. Wetted parts are made from ETFE, PA6T/6I (40% GF), and EPDM, with an ingress protection rating of IP65.

Electrical Specifications
Output options include analog and pulse, with power supply requirements ranging from 4.75 to 33 Vdc. Current consumption is less than 50 mA for analog and less than 2 mA for pulse outputs.

Model Number Identification
Model numbers indicate maximum flow, output type, and additional features like display.

> Introduction Mass Flow ONLINE B.V. sells flow measuring and controlling products through the internet. From the website www.massflow-online.com flow meters or controllers can be ordered 24 hours a day 7 days a week. Most products are in stock and will be shipped world-wide within two working days. > Description The new LIQUI-VIEW Base series offer a compact, lightweight and cost-effective solution for monitoring the flow or consumption of cleansing water, cooling water or spa water. The unique sensor body and transmitter design makes LIQUI-VIEW Base one of the most compact, lightweight vortex meters in the industry. > LIQUI-VIEW Base series The LIQUI-VIEW Base series operate on the vortex principle. The obstruction (bluff body) placed in the flow of the liquid sheds vortices downstream at a frequency proportional to the velocity of the liquid. This pattern of vortices is named the Von Karman vortex street. A piezo-electric sensor detects the vortices and creates electrical pulses which are proportional to the liquid flow rate. The instruments may be mounted in any position. LIQUI-VIEW Base flow meters can be supplied in ranges from 0,5 l/min up to 150 l/min at max. 12 bar pressure rating. Furthermore the instruments can be supplied with a display for local readout and analog output or a pulse output. > LIQUI-VIEW Base features ♦ No moving parts makes it: - Impervious to deposits of hard water - Maintenance free ♦ Low pressure drop ♦ Mounting in any position ♦ Wide flow ranges ♦ Fast response ♦ Suitable for dirty water (circulating, well or filtered waste water) ♦ Sustainable product design - Low power consumption - Lightweight and compact ♦ Available with a tilting display for local read out > Fields of application ♦ Drinking water ♦ Cooling water monitor ♦ Deionized water (RO/DI skids) ♦ Ultra pure water distribution (medicare, biotech, semiconductor, pharmaceutical) Q = flow rate in l/min Example for LVB-06-A used at a flow rate of 8 l/min: (240 * 82) / 100 = 153.6 mbar Mass FlowONLINE
