Four Ways to Install
a Halogen Sensor

Selecting the right mounting configuration is key to accurate readings, long sensor life, and easy maintenance. Select a certified sensor and compatible mounting assembly for direct drinking-water contact. Direct-pipe and immersion configurations can avoid a dedicated sample-to-drain stream.

Wet-Tap with Remover

Live pipe insertion — no shutdown required

The wet-tap mount allows sensor installation and removal without shutting down the process line, making it ideal for continuous systems and live distribution mains where downtime is not acceptable.

Best For

Distribution system mains
High-pressure lines up to 145 PSI
Remote monitoring sites

Easiest Install

Halogen D20 Controller with MP Sensor — side-stream wall-mounted system

MKIT

Side Stream (MKIT)

Wall-mounted flow cell — easiest install

The MKIT side-stream configuration diverts a small flow of process water through a separate, low-pressure wall-mounted flow cell (maximum 60 PSI) where the sensor is housed. The ideal starting point and great for demos.

wallWall-mounted — no floor drain or sample panel required
recyclingSide stream can return water to process (NSF-61)
boltFastest and easiest installation — great for demos
swap_horizIdeal for replacing old instruments where wet-tap isn't practical
verifiedLow-pressure design — max 60 PSI

Best For

Treatment plants with existing plumbing
Equipment replacement without re-piping
In-plant free chlorine monitoring
Demo and evaluation deployments

Immersion

Open tanks, basins & reservoirs

Immersion-style mounting suspends the sensor directly in open tanks, basins, clearwells, or large channels. No pipe connection required — use a sealed immersion assembly at an approved depth, with suitable support and cable protection.

MP-5F: D-H2MF-P / MP-TOTAL: MP-T-H2MF-P

PVC Tee (Pipe Install)

Direct inline — lowest cost option

The PVC tee mount integrates the sensor directly into a pipeline using standard plumbing fittings. The most economical installation option — no waste stream, no bypass, just a standard tee in the pipe.

Quick Selection Guide

Answer these questions to narrow down the right mount for your site.

Can you shut off the line?

Yes →PVC Tee (D-H2MF-P)

No →Wet-Tap (D-H2WT-P)

Is it an open tank or reservoir?

Yes →Immersion (D-H2LF-P)

Do you need wall mounting at a treatment plant?

Yes →Side Stream MKIT

Need the lowest cost solution?

Yes →PVC Tee (D-H2MF-P)

Maximum pressure above 60 PSI?

Use Wet-Tap or PVC Tee (both rated 145 PSI). MKIT max is 60 PSI.

Still not sure? The Product Selector walks you through it step by step.

Match the sensor, mount and operating limits

Confirm drinking-water certification, sensor compatibility and the pressure and temperature limits of the complete assembly. A side-stream installation also needs a suitable sample-water return or drain arrangement. Use the Product Selector to get the right combination for your site.
