Glass Tube Variable Area Flowmeters | DS3601-100mm

Glass Tube Variable Area Flowmeters - Overview

This Glass Tube Flowmeter uses a 100mm scale length borosilicate glass tube and a float. As it is based on the variable area (VA) principle, these flowmeters provide clear, simple and reliable operation. They are individually scaled and calibrated according to the customer's requirements. The fluid or gas flows vertically upwards through the tapered glass tube, causing the float to rise to an equilibrium position. The flow rate is measured by reading the top edge of the float against the scaled tube. Suitable for use with gasses or water (eg. cracked ammonia, helium, hydrogen, methane, nitrogen, oxygen, propane).

Glass Tube Variable Area Flowmeters - Features
- Instantaneous response

Platon Fire Sprinkler Flowmeters | DS1163

Platon Fire Sprinkler Flowmeters - Overview

This is a robust, compact direct reading flowmeter, approved for use on lines from 80-150mm. Suitable for use in automatic sprinkler installations, water spray or deluge systems. Approved for regular monitoring and testing of such systems by the Loss Prevention Certification Board (LPCB), under their “Rules for Automatic Sprinkler Installations”, in the UK and equivalent organisations in other countries. The flow meter is a combination of two simple measuring elements. In the main flow line, an orifice plate is inserted between two pipe flanges, producing a pressure drop related to the flow rate. Across the orifice plate, a shunt or bypass loop uses this pressure drop to create a small flow through a similar orifice restrictor and a Variable Area flowmeter. The flow in the bypass VA meter is proportional to the main line flow, and special scaling on the glass tube allows the main line flow to be measured directly.

Platon Fire Sprinkler Flowmeters - Features
- Approved and listed by LPCB
- Easy installation between pipe flanges
- Instantaneous reading
- Simple water flow measurement
- No electrical power needed
- Isolation valves for tube replacement and cleaning
